Note - some models have different dimensions for these screws, for example, longer ones.

Note - older models of the Carl Zeiss Jena Lg microscope use a different screw.

Note - the small screw at the front of this part unscrews in the OPPOSITE direction than most screws, and this is the most common cause of damage.

Note: Please examine the photos carefully. If I have more than one of this part, some of the screws may show traces of improper (forceful) unscrewing. These are not major traces - mostly minor scratches. Of course, they do not affect the functionality of the element at all.

Note - some models have different screw dimensions, for example, longer ones.

Note - in microscopes with a centering stage holder (for polarizing stages), this screw may be different.

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

4 mo2 condenser holder that was used in the Carl Zeiss Jena Ergaval microscope. The same condenser (but with a different lower lens) is used in an identical holder in Fluoval microscopes. Condenser holders with such screws can also be found in the following microscopes:
- 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.

In the photo gallery there are detailed photos of this element together with the dimensions. Additionally, in the last photo an arrow indicates which element is being referred to and where it is located in the microscope head, in order to clearly identify this part.

Both the left and the right knob are identical, but when installing be careful about the screw length, as they may differ).

VERY IMPORTANT: although the right and left knobs are identical - different screws are used to attach them.

Lengths of screws used to attach the knobs in Carl Zeiss Jena Ergaval and Amplival microscopes:
- left fine adjustment knob (micro): 1 pc. screw 12 mm
- left coarse adjustment knob (macro): 3 pcs. screws 8 mm
- right fine adjustment knob (micro): 1 pc. screw 16 mm
- right coarse adjustment knob (macro): 3 pcs. screws 12 mm

Over the years these plastic knobs are often damaged:
- sometimes they crack due to impact or improper transport securing
- often they are partially melted by a soldering iron, light bulb or even a cigarette
- sometimes they are damaged during attempts to remove them

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

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".

Description of this part for the microscope.

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.

Description of this part for the microscope.

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

The last photograph includes an excerpt from the original manufacturer's documentation. An arrow indicates this exact model of condenser holder, making it easy to identify the component.
