Gleitfett grades differ in their parameters.

Gleitfett I E10 and Gleitfett II E75 were supplied with the Carl Zeiss Jena micromanipulator.
The Gleitfett III E410 offered here was supplied with the Carl Zeiss Jena Neophot-21 microscope.

This MAY suggest (although I have no proof in the form of manufacturer documentation) that the lower numbers (I and II) and the lower values of the "E" parameter (E10 and E75) were intended for finer mechanisms - and may therefore have a lower viscosity, for example. The III E410 grease, with its high "E" value, was supplied with a heavy microscope built around massive mechanics - so it may well be thicker.

This grease can of course be used on microscopes from other manufacturers as well - a few are listed in the "compatibility" section, but that is by no means a complete list.

Info: PI = polarization-interference objective (red ring).

Compatible with the following PZO condensers:

- slit condenser
PI objectives are among the components of the PZO UPI set (i.e. the so-called DIC).

VERY IMPORTANT: the marking on the objective is "PI" (in lowercase: "pi"), meaning [P]-polarization [I]-interference.
In many descriptions available on the Internet, you can find information that this is a PLAN objective. This is an ERROR caused by misinterpreting the marking as PL.

Note: another INCORRECT piece of information often found online is that these are DIC objectives. This is not true.
DIC according to Pluta (niem: DIC nach Pluta), sold by PZO, achieves the DIC effect (i.e. a 3D relief image) using standard achromatic PZO objectives (and not only those). Objectives marked PI with a red ring are not required for this.

It can be used with any microscope from any manufacturer that supports RMS objectives, TL=160 mm, FL=45 mm.

Manufacturer: Lomo
Magnification: 20x
Model: 20 0.40 P
Numerical aperture: 0.40
Tube length: 160 mm
Focal length: 33 mm
Cover glass: yes, 0.17 mm
Thread: RMS + Pol adapter
Info: P = Polarization

This is an objective designed for transmitted light work with a cover glass.

The RMS thread objective is mounted on a dedicated slide-in adapter that allows it to be used in Lomo MIN series and Lomo Polam series microscopes. Of course, the objective can be unscrewed and another objective can be mounted in the adapter.

The objective itself, once removed from the adapter, is a standard objective that can be used in virtually any microscope with an RMS thread. It is a so-called "short objective" (focal length 33 mm). When a 12 mm adapter is added, the total length becomes 45 mm, allowing it to be used with newer microscopes from any manufacturer.

Lomo polarization objectives with RMS thread can be installed in an RMS-M27 adapter and then used in microscopes such as Lomo Biolam M, Lomo Biolam I, Lomo Lumam, or Lomo ML-2. I have also frequently seen such objectives used in Zeiss Axio series microscopes with M27 thread.

The Pol adapter also allows precise centering of the objective relative to the entire optical path - this requires tools (keys / tools).

Info: I have repeatedly seen information stating that this RMS-Pol adapter is compatible with Leitz Wetzlar polarization microscopes - however, I have not personally verified this.

In summary, this objective is dedicated to Lomo MIN-1, MIN-4, MIN-5, MIN-6, MIN-8, Lomo Polam R-113, Polam L-211, Polam L-213, Polam R-311, Polam LMPR microscopes - but it is practically compatible with any microscope from any manufacturer that supports 160 mm objectives.

Additionally, this objective is very often used for macro photography even without a microscope. This objective does not require a cover glass and works in the "direct-projection" technique, meaning it can be connected directly to a camera without additional optics. This allows achieving a very high magnification scale and great depth of field across the entire image when using focus stacking. The fact that this is a polarization objective (i.e. stress-free optics without internal glass tensions) further improves image quality at high magnifications.

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

- 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.

Focal length: 45 mm
Cover glass: yes, 0.17 mm
Immersion: yes, oil
Thread: RMS
Specimen protection: yes - spring-loaded
Info: PHACO 3 = phase contrast

Some important information about this objective:
- the designation "EF" means "Extended Field" - this is a semi-plan achromatic objective with an 18 mm field of view, which should be taken into account when selecting suitable eyepieces
- the semi-plan achromatic correction is "almost flat" - it is no longer an achromat, but not yet a plan achromat
- this objective can be used in brightfield, but phase contrast operation requires a compatible phase contrast condenser or a slide (slider) with a phase ring diaphragm
- the designation PHACO 3 means that for phase contrast operation a phase contrast condenser set to ring "3" should be used (the equivalent setting used by Zeiss is called "Ph3")
- this objective can be used with microscopes designed for objectives with a 170 mm tube length, but in such a case the optical path must be extended by 10 mm - most commonly by pulling the eyepieces out of the tubes by 10 mm

This objective can be used with any microscope from any manufacturer together with a compatible phase contrast condenser. Naturally, the microscope must be compatible, i.e. it must support RMS objectives, TL=160 mm and FL=45 mm - or have adapters that make such adaptation possible (for example thread adapters).

Manufacturer: Lomo
Model: PLAN 25x0.50 P
Original designation: ЛОМО ПЛАН 25х0,50 П
Magnification: 25x
Numerical aperture N.A.: 0.50
Tube length: 160 mm
Cover glass: yes, 0.17 mm thickness
Immersion oil: no - this is a dry objective
Focal length: 45 mm
Thread type: RMS
Additional designation: P (Cyrillic: П) indicates that this objective is designed for use with polarized light
Special features: built-in iris diaphragm
Year of manufacture: 1976

This objective has a standard RMS thread and TL=160 mm, which means it can be used with the vast majority of microscopes from virtually any manufacturer, including Olympus, Zeiss, Nikon, PZO, Carl Zeiss Jena, Reichert, Wild and many others.

The built-in iris diaphragm allows, among other things, precise centering of the objective, because in a polarizing microscope the following diaphragms may operate simultaneously:
- field diaphragm in the illuminator
- aperture diaphragm (or two aperture diaphragms) in the condenser
- iris diaphragm in the microscope objective
- iris diaphragm in the eyepiece head
and accurate centering of all of them relative to each other is very important in polarized-light observations.

Objectives marked "P" / "Pol" feature a special construction in which the lenses are mounted and cemented in a way that prevents mechanical stress. They can be used both for conventional brightfield microscopy and for observations in polarized light.

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.
