- low magnification for observing macro objects with side illumination, without a cover glass (e.g., 2.5x / 3.2x / 5x / 8x / 10x)
- for phase contrast
- for various phase contrasts (positive, anoptral, amplitude, Zernike)
- for DIC
- for water immersion (e.g., Lomo)
- all for oil immersion (e.g., Leitz 10x Oil / 25x Oil / 40x Oil / 100x Oil)
- apochromatic for better color
- for polarization
- only high magnifications, e.g., for analyzing cell wall ornamentation (50x / 63x / 80x / 100x)
- for darkfield work (objectives with an iris diaphragm in the center)

Therefore, having only one microscope we can use it for different purposes and not screw in and unscrew all the lenses manually each time.

integrated gear for adjusting the height of the microscope condenser, as well as a rack with the element on which the condenser holder is mounted.

Description of this part for the microscope.

a glass frosted filter (so-called ground glass) is located in the optical light beam path. It is mounted on a steel rod ending with a handle positioned outside the microscope base - at the rear, next to the place where the illuminator is inserted. This handle is used to insert and withdraw the frosted filter from the illumination beam path.

This design often leads to damage:
- the glass frosted filter is mounted on the rod in such a way that the glass frequently cracks
- the handle located at the rear of the microscope base very often breaks or crumbles
- the metal rod often jams and as a result of attempts to move it - bends

Here I present and offer this exact frosted filter with the complete movement mechanism:
- glass frosted filter (ground glass)
- holder for mounting the filter to the rod
- all necessary screws to attach this set to the microscope base
- plastic control knob for operating the ground glass

Description of this part for the microscope.

This diaphragm is necessary to set illumination according to the Koehler system.

This element is used in a diaphragm installed in various Carl Zeiss Jena microscope models built on the Amplival stand:
- Amplival
- Amplival Interphako
- Amplival Pol
- Vertival
- Peraval
- Fluoval
- Docuval

The field diaphragm located in the microscope base is part of the transmitted light path - it is not a diaphragm for EPI (reflected) illumination. However, it is VERY LIKELY that individual blades may also fit reflected light diaphragms and other diaphragms (e.g. aperture diaphragms) in Carl Zeiss Jena microscopes and condensers.

Damage to iris diaphragm blades is one of the more common failures in Carl Zeiss Jena microscopes. Most often this occurs when:
- the lubricant in the diaphragm opening / closing mechanism dries out and the user tries to move it by force
- a foreign object gets between the blades (e.g. a glass fragment from a chipped microscope slide)
- the diaphragm is closed too quickly or opened too far

In the event of an iris diaphragm failure, it is possible to:
- replace the entire element (condenser or diaphragm module)
- replace only the diaphragm
- repair the diaphragm by replacing the damaged blades

- and a mounting screw

The mounting screw itself - as a separate component - fits practically most Carl Zeiss Jena microscopes based on the Amplival system:
- Amplival
- Amplival Interphako
- Amplival Pol
- Vertival
- Peraval
- Fluoval
- Docuval

Carl Zeiss Jena developed a complete modular microscope system based on connections made with this type of screw. Thanks to this design, the screw as a service part is also compatible with most accessories, modules and components that can be mounted to the microscope, including:
- EPI arms
- Parktaric Zoom Tube module
- Interphako heads

Important - carefully check the shape and dimensions of the screw to make sure it is the size you need. For example, the modular design of the Carl Zeiss Jena Jenamed microscope is based on mounting screws of a different shape and size (search for it in this database for comparison).

- Docuval
- Amplival
- NU-2

The purpose of this spring screw is to push the clamp in which the condenser is mounted outward. Thanks to the spring integrated in the screw, it is possible to center the condenser using long centering screws (you can find such a centering screw in the database under number 99132).

In the last photo, an arrow clearly indicates which screw is meant and where it is mounted in the condenser holder.

There are several models of mechanical microscope stages from Carl Zeiss Jena designed for microscopes of the Mikroval series. They differ mainly in the placement of the control knobs used for movement in both axes, for example:
- the Ergaval model has a short handle with control knobs
- the Amplival model has a long handle
- some variants of the Laboval model had a stage without a handle with control knobs, where the knobs were arranged horizontally on both sides of the stage.

However, many of the individual components used in these stages are identical.

Many of these stages can also be used interchangeably with other microscopes of the Vertival series, which means that many microscopes today no longer have their original stages. For this reason it is best to examine the photos carefully to make sure that the element shown and offered here will fit.

- for polarization
- only high magnifications, e.g., for analyzing cell wall ornamentation (50x / 63x / 80x / 100x)
- for darkfield work (objectives with an iris diaphragm in the center)

Therefore, having only one microscope we can use it for different purposes and not screw in and unscrew all the lenses manually each time.

In microscope models with fluorescence illumination (e.g. Laboval Fluoreszenz or Fluoval), a filter wheel is installed in this head. When the manufacturer installed this head in other microscope models - a blanking plug was placed instead of the filter wheel - and this is exactly the element shown here.

Over the years, this element is very often lost and on the secondary market there are many such photo trino adapters without the blanking plug. The lack of this blanking plug can cause even large contaminants to enter the optics.

meaning the shaft with focusing knobs mounted on both ends on the sides of the microscope. Part of this shaft contains a toothed rack, or more precisely speaking, it is a toothed shaft. In the item shown and offered here, the fine focus knob (micro focus) is mounted on the left end of the shaft. Please note that the left and right knobs are identical - however, screws of different lengths are used to attach them: the left knob is attached with a 12 mm screw, while the right knob uses a 16 mm screw. Detailed information about the screws used to attach the coarse and fine focus knobs can be found here: https://www.facebook.com/MikroskopyPZO/posts/pfbid0x2tFPHAEqjn4B7BRsvm2vAt9yyuuSM836QS6K4951GqeUFpU2FJH8YXfFFxbz3cPl

Such focus shafts are used in the following microscopes:
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival (and its variants: Fluoval, Epival, Vertival, Interphako)
- Carl Zeiss Jena Metaval
- Carl Zeiss Jena Docuval

This coarse and fine focus shaft may help solve the following problems in Carl Zeiss Jena Ergaval / Amplival microscopes and related models:
- if the shaft became bent, causing a noticeable jump while rotating it (a very common failure)
- if the screw holding the fine focus knob broke off or snapped, leaving part of the screw inside the shaft
- if the left fine focus knob is missing or damaged
- if the thread on the right or left end of the shaft, where the fine focus knobs are attached, is damaged
- if the toothed rack on the shaft (because such a shaft is effectively a toothed shaft) becomes damaged

for taking microscope photographs or recording microscope videos. This is a gray photographic adapter.

Basic technical parameters:
- mounting connection to microscope stand: 41 mm dovetail
- output connection type on the photo port: 49 mm internal thread
- connection for binocular head mounting: Jena standard 41 mm dovetail
- magnification directed to the binocular head: 1.6x
- magnification on the photo output: none (that is 1.0x)

Because this photo head has a 49 mm threaded output, virtually any device, camera, adapter, tube or other accessory can be connected after using an appropriate 49 mm thread adapter. Direct projection technique may be used (because there is no additional optics inside), or any projection eyepieces may be installed in the optical path.

This photographic attachment is intended mainly (but not exclusively) for the following microscope models:
- Carl Zeiss Jena Eduval
- Carl Zeiss Jena Laboval
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival
- Carl Zeiss Jena Vertival
- Carl Zeiss Jena Epival
- Carl Zeiss Jena Metaval
- Carl Zeiss Jena Telaval
- Carl Zeiss Jena Pictoval
- Carl Zeiss Jena Epignost

The list above contains Mikroval series microscopes with gray housings - just like the tube shown and offered here. However, it also works with older black Carl Zeiss Jena microscopes:
- Carl Zeiss Jena L-Stativ (models Lg, Lu and Lr)
- Carl Zeiss Jena Lumipan
- Carl Zeiss Jena Ng
- Carl Zeiss Jena Nf (and NfPk)

Please note that microscopes from other manufacturers also use the 41 / 41.5 mm dovetail connection standard. Because of this, this photographic head can also be used with microscopes made by:
- Lomo (for example Lomo Biolam)
- Meopta
- IOR
- selected Reichert microscopes (for example Reichert Neozet)
- Will Wetzlar
- Hund Wetzlar
- Leitz Wetzlar

This Carl Zeiss Jena tube is also very often used with microscopes having a larger head mounting diameter. In such cases users apply additional spacer or thickening rings. Because of this, this photo adapter also fits microscopes from manufacturers such as:
- PZO (for example the PZO Biolar model with 43 mm connection)
- Olympus (for example the Olympus CH model with 42 mm connection)

The element that allows a photographic camera or imaging camera to be connected to Carl Zeiss Jena Mikroval series microscopes may be referred to by different names. Commonly used names include:
- trino head
- trinocular head
- photo head
- photographic head
- photo attachment
- photographic attachment
- photo adapter
- photographic adapter
- photo tube
- photographic tube
- phototube
- photographic angle tube
- and various combinations of the words head, attachment, adapter or tube with terms such as photo, photographic, for camera and similar

related models.

This element is used when the microscope does not have a transmitted light illuminator with a lamp holder installed in the rear part of the base. In such a case, so that there is no open hole and no contamination can enter the inside of the microscope, this opening can be closed with this blanking plug.
When can such a situation occur that the microscope does not have a transmitted light illuminator? Most often when the microscope is intended for reflected light work only and simply does not have any DIA illuminator (transmitted light illuminator).

This element fits the following microscopes:
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival
- Carl Zeiss Jena Epival
- Carl Zeiss Jena Vertival
- Carl Zeiss Jena Interphako
- Carl Zeiss Jena Fluoval

and related models.

This element is used when transmitted light is temporarily not needed. The illuminator itself does not need to be removed - instead, the light output should simply be completely blocked, and this light output is the collector lens itself. This collector lens is located inside the microscope base, above the angle mirror and below the condenser.

When can there be a need to completely block transmitted light? Most often when:
- a microscope with DIA illumination (transmitted light) and EPI illumination (reflected light) is available, but temporarily only reflected light operation is needed
- a microscope previously working with transmitted light (for example Carl Zeiss Jena Amplival) is being converted into a microscope intended to work permanently only with reflected light (for example converting an Amplival into a Vertival)
- for example a Fluoval microscope is used and it is undesirable that "the lower light is visible"

This element fits the following microscopes:
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival
- Carl Zeiss Jena Epival
- Carl Zeiss Jena Vertival
- Carl Zeiss Jena Interphako
- Carl Zeiss Jena Fluoval
- Carl Zeiss Jena Docuval

Jena
Name: Grossfeld Binocular
Eyepiece mounting diameter: 30 mm
Microscope mount: 41 mm dovetail mount
Diopter adjustment: yes, for one eyepiece

The set also includes two eyepieces:
- Model: Carl Zeiss Jena GF-Pw 10x (25)
- Mounting diameter: 30 mm

This head is most commonly used in the following microscopes:
- Carl Zeiss Jena Jenamed
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenapol
- Carl Zeiss Jena Jenvert
- Carl Zeiss Jena Jenatech
- Carl Zeiss Jena Jenalab

Interestingly, widefield binocular heads with a 30 mm eyepiece mounting diameter are sometimes also installed in older Mikroval series microscopes (for example Ergaval and Amplival). If the microscope is additionally equipped with GF-Planachromat series widefield objectives (or GF-Planapochromat objectives used in Docuval microscopes) - this creates the best possible combination for Carl Zeiss Jena microscopes with a 160 mm tube length.

This microscope head model is identical to the Baader Mark V binocular viewer used in astronomical telescopes and is often purchased by astronomy enthusiasts and adapted for telescope mounting.

and the nosepiece is mounted from underneath.

Based on the Carl Zeiss Jena Amplival microscope, whose modular design allows for various configurations, several microscope models were created:
- Vertival
- Epival
- Amplival Interphako
- Amplival Pol
- Fluoval
and these microscopes differ from each other, among other things, by different arms. The arm from the Amplival model has the simplest construction.

By owning different arms and one microscope - you can swap them according to your needs and use different functionalities, as if you had two microscope models.

This element consists of the following components:
- fixing screw securing the arm to the microscope body
- holder enabling the mounting of components with a 41 mm mounting diameter (e.g. binocular head)
- fixing screw securing this component (e.g. head). This element is very often damaged.
- guides (slides) enabling the attachment of an interchangeable nosepiece

A device with a matching mounting diameter that is placed on the arm from above can be, for example:
- head with a built-in inclined tube
- intermediate tube (German: Zwischentubus)
- magnification changer (Optovar)
- EPI reflected light illuminator
- polarization analyzer module
- and others, because as mentioned above, the Amplival class microscopes have a modular design and there are many accessories available for them

This microscope arm can solve the following issues related to Carl Zeiss Jena Amplival class microscopes:
- if your microscope is missing this element, which happens with microscopes available on the secondary market
- if you own another variant of a microscope from this class, e.g. Carl Zeiss Jena Vertival, and you want to convert it into a "regular" Amplival
- if you own such an arm, but it is of poor quality or has damaged individual components
- if you need one of the component parts of this arm
- if you are building your own DIY project and need a mount compatible with the Carl Zeiss Jena standard

On the last photo, an arrow indicates which element it is and where it is located in the microscope to clearly identify this part.

Important: The popular and visually very similar Carl Zeiss Jena Ergaval microscope, which is often confused with the Amplival model, DOES NOT HAVE such a modular design and this arm does not fit it.

If you need any of the component parts of this arm (e.g. the large fixing screw securing the arm to the microscope stand or the smaller fixing screw securing the head to the arm - search this database or contact us by writing an email.

Amplival microscope
Number of lenses: 3
Numerical aperture N.A.: variable, from N.A. 0.16 to N.A. 1.4
Aperture diaphragm: yes, screwed on as a detachable module

The Carl Zeiss Jena pancratic condenser has three upper lenses:
- for working with low magnification objectives (usually up to 6.3x)
- Apl. 1.4 for working with high magnification objectives
- an oil immersion cardioid darkfield lens with N.A. = 1.05

Mechanically, this condenser is mounted on dovetail rails located on the microscope stage holder block.

Here are the mounting possibilities of the pancratic condenser to Carl Zeiss Jena microscopes:
- to Amplival, Docuval, Epival, Fluoval, Vertival microscopes, this condenser can be mounted directly
- to Ergaval, Nu, Nu 2, Nf microscopes, this condenser is mounted after unscrewing the aperture diaphragm from it
- to Jenaval, Jenapol, Jenalumar microscopes, this condenser can also be mounted, but it is installed together with the entire stage holder block from the Amplival microscope http://www.microscopy-uk.org.uk/mag/artfeb09/rs-jenalumar.html
- be careful, because the Lumipan microscope also features a pancratic condenser, but with a completely different mounting method

This condenser is often used as a "parts donor" for own DIY projects, for example:
- the Apl. 1.4 lens is often used to modify (upgrade) condensers with a lower numerical aperture N.A. in various microscopes
- the darkfield lens is very often used to build a standalone cardioid condenser
- the iris diaphragm has a very wide range of applications

On the last photo, an arrow indicates which element it is and where it is located in the microscope to clearly identify this part. Additionally, the attached video shows how the individual elements of this condenser move.

As far as I know, the same mechanism is used in the following Carl Zeiss Jena microscopes:
- Ergaval
- Amplival
- Fluoval
- Vertival
- Epival
- Docuval
- Metaval
- Peraval

This component is installed onto the shaft by sliding the internal tab into the keyway groove on the shaft. After tightening the round slotted nut, a locking mechanism is created that prevents the nut from loosening on its own due to vibration.

As far as I know, the same mechanism is used in the following Carl Zeiss Jena microscopes:
- Ergaval
- Amplival
- Fluoval
- Vertival
- Epival
- Docuval
- Metaval
- Peraval

This component acts as a resistance regulator and functions as a friction brake. Tightening the outer element compresses the tapered section of the bushing, causing the slotted bushing to contract at the slit. This increases friction on the shaft and makes the entire mechanism move with greater resistance.

Note - in some descriptions available on the Internet, this component is referred to as a "piece of wood".

Jena
Version: grey version, removed from a Carl Zeiss Jena Amplival microscope
Mounting method: aperture diaphragm in the form of a detachable module
Centerable: yes

This iris diaphragm module is mechanically mounted to the bottom of the panchromatic condenser.

In Carl Zeiss Jena panchromatic condensers, the diaphragm is designed as a detachable module because it can be removed and replaced, for example, with a phase contrast module or a polarization module. Precisely because this microscope part can be detached, it is often missing from condensers available on the secondary market - over the years it simply gets lost.

Interestingly, this microscope part is very often modified. When users do not have a phase contrast module or a polarization module, they frequently insert polarizing film or custom-made phase rings into the aperture diaphragm module and obtain the functionality they need through DIY modifications.

This module can also solve a common problem found in Carl Zeiss Jena Amplival microscopes, namely damaged diaphragm blades in the condenser.

Zeiss Jena
Model: Apl 1.4
Holder name according to the manufacturer's catalogue: Kondensor-Einhänger mo
Condenser name according to the manufacturer's catalogue: Aplanatischer Kondensor 1.4 mo / ms
Version: grey version from a Carl Zeiss Jena Ergaval microscope (as opposed to the black version used, for example, on Carl Zeiss Jena Nf microscopes)
Numerical aperture N.A.: 1.4
Aperture diaphragm: yes, mounted in the condenser holder
Wide-field lens: yes, swing-out type
Removable top lens: yes, unscrewable
Mounting diameter: the optical section (the condenser without the iris diaphragm) has a mounting diameter of 39.5 mm and can be unscrewed from the condenser holder

The complete assembly consists of the following components:
- upper Apl 1.4 lens
- removable condenser (mo / ms)
- iris diaphragm attached to the condenser holder
- condenser holder mo
- swing-out wide-field lens
- two centring screws

The last photograph in the gallery shows a page from the manufacturer's original catalogue. Arrows indicate both this exact condenser holder model and the matching condenser.

Mechanically, this condenser is mounted using a dovetail guide located beneath the microscope stage. On the Carl Zeiss Jena Ergaval this is a separate condenser mounting assembly, while on the Carl Zeiss Jena Amplival the dovetail is integrated into the microscope stage support assembly.

unscrewed. It is mounted onto the dovetail guide located underneath the microscope stage carrier and secured with a clamping screw.

Carl Zeiss Jena Ergaval microscopes were originally equipped with a condenser attached to the "MO" holder. This holder has a permanently mounted iris diaphragm and wide-field lens, while the condenser itself is screwed into the upper thread. In this configuration, the condenser cannot be exchanged.
The Carl Zeiss Jena Fluoval uses a similar arrangement, whereas the Carl Zeiss Jena Amplival was originally equipped with a panchromatic condenser.

If the user wishes to use other condensers (including those made by manufacturers other than Carl Zeiss Jena), the original condenser holder must be replaced with the MZ condenser holder. Once this has been done, any microscope condenser with a mounting diameter of 39.5 mm can be installed. Condensers with a 37 mm mounting diameter can also be used if they are fitted with a suitable adapter ring.

This is exactly such a holder for interchangeable condensers.

Basic specifications:
Manufacturer: Carl Zeiss Jena
Original documentation name and model: Kondensor-Einhänger MZ
Colour: grey, the version manufactured for the Mikroval microscope series
Internal diameter: for mounting condensers with a 39.5 mm mounting diameter (for example the Carl Zeiss Jena cardioid darkfield condenser)
Condenser retaining screw: yes, central condenser clamping screw
Centering screws: yes, two condenser centering screws
Microscope mounting: dovetail

Although this component is grey, it is also compatible with older black Carl Zeiss Jena microscopes from the 1950s and 1960s (it simply will not look completely original unless it is repainted).

This condenser holder is compatible with, among others:
- Carl Zeiss Jena Ng (black microscope)
- Carl Zeiss Jena Polmi-A (black microscope)
- Carl Zeiss Jena Nf (black microscope)
- Carl Zeiss Jena Nu (the NU-2 version is grey)
- Carl Zeiss Jena Ergaval (grey microscope)
- Carl Zeiss Jena Fluoval / Fluoval-2 (grey microscope)
- Carl Zeiss Jena Amplival and its variants (grey microscope)
- Carl Zeiss Jena Docuval (grey microscope)

Various names are used for this microscope component, including:
- condenser holder
- condenser carrier
- condenser mount
- condenser support

reflector, performs two functions:
- it contains a barrier filter (emission filter) for the 450 nm wavelength
- it acts as an angular mirror, reflecting the light beam from the EPI fluorescence illuminator vertically downward through the objective toward the specimen.

This fluorescence filter cube fits the following EPI fluorescence microscopes:
- Carl Zeiss Jena Fluoval Fluoreszenz
- Carl Zeiss Jena Fluoval-2 (built on the Carl Zeiss Jena Amplival microscope platform)

Important – this microscope component does not fit the first version of the Carl Zeiss Jena Fluoval microscope. The Fluoval microscope (without "2") does not use a filter cube. Instead, it has a simple permanently mounted swing-out barrier filter.

The filter cube has two positions:
- empty, for normal transmitted-light operation
- 450 nm for reflected-light fluorescence (EPI) operation

Mechanically, this filter cube is installed between the objective nosepiece and the microscope head. It slides into a dedicated slot and moves along a dovetail guide. On the Carl Zeiss Jena Laboval Fluoreszenz microscope, this slot is located in the additional upper horizontal arm of the EPI fluorescence illuminator. On the Carl Zeiss Jena Fluoval-2 microscope, the slot is located in the EPI fluorescence arm, which is an integral part of the microscope. The Fluoval-2 is based on the Carl Zeiss Jena Amplival microscope, which has a modular design. Mechanically, the Fluoval-2 is essentially an Amplival equipped with an upper EPI fluorescence arm.

Sliding the cube along this dovetail guide switches between the empty position (transmitted light) and EPI fluorescence with the 450 nm filter.
