dozens of fluorescence illuminator models. Many of them use the same type of lamp holder, but not all. Unfortunately, the catalog number of the illuminator to which this holder fits is unknown.

Description of this part for the microscope.

compatible with microscopes designed for a 45 mm parfocal standard It is mounted between the objective and the nosepiece/revolver so that optical focus is maintained despite the additional mechanical extension.

Leitz PLEZY differs from extension adapters available on the market in that it features internal anti-reflective optics, ensuring that despite the mechanical extension of the focal length the image quality is not degraded.

- lens mount marked: 0.8x 419610 (font characteristic for the Wild company. Number 419610 is the manufacturer catalog number)
- field widening lens: 0.8x MPS 195182 (number 195182 is the catalog number of this lens)
- Wild Leitz / Wild MPS 52 photo tube (Heerbrugg Switzerland) with connector for the MPS 46 control console (important - the console is not included)

The mounting diameter on the microscope side is 40 mm.

This tube is currently commonly used for connecting digital cameras or photographic cameras to microscopes with a trinocular head. There is a lot of information about this online as well as DIY step-by-step guides on internet forums. It allows taking microscope photographs and, after minor modifications, it can also be used for macrophotography https://www.mikroskopia.de/serv-mps52-en.html.

Please note that the MPS 52 was sold during a period of ownership and manufacturer name changes. Leitz Wetzlar changed its name to "Leica", and Leica later acquired Wild Heerbrugg. Because of this, the following names are used interchangeably for the entire MPS 52 system:
- Wild MPS 52
- Leitz MPS 52
- Leica MPS 52
This is also visible on the element shown in the photographs:
- the adapter for Polaroid film backs is marked as Wild Heerbrugg
- while the tube itself carries the "Wild Leitz" logo

Wetzlar
Model: 160/0,17 EF 100/1.25 OEL PHACO 3
Magnification: 100x
Correction: semi-plan achromat
Numerical aperture: 1.25
Tube length: 160 mm
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).

not intended for so-called "thick" objectives
Thread in the cap: no, the cap of this objective case does not contain a thread for attaching an RMS objective

This objective case can be used to store so-called "short" objectives (DIN 33 mm), longer objectives (DIN 37 mm), and long objectives (DIN 45 mm), provided they are not the so-called "thick" type.

Various names are used on the secondary market for a microscope objective case, including:
- objective case
- microscope objective case
- objective container
- microscope objective container
- objective storage case
- objective storage container
- objective box
- objective storage box
- protective objective case
- objective lens case
- objective lens container
- dust protection case
- transport case for microscope objectives
- microscope objective holder case
- storage canister for microscope objectives

Each case has the Leitz Wetzlar logo on its cap.

Although this case is of greatest interest to users and collectors of objectives made by the manufacturer Leitz Wetzlar, it can of course be used to store objectives from any manufacturer.

Description of this part for the microscope.

microscopes have a standardized mount of 38 mm diameter into which various tubes can be fitted. One of exactly these tubes is presented here.

Basic parameters of the tube presented here:
Markings on the housing: "Germany" on one side and "30ø" on the other side
Mounting connection: a plain tube (cylinder). This is not a tube with a thread or a dovetail
Mounting diameter: 38 mm, that is the standard mounting diameter used in Leitz Wetzlar trinocular heads
Internal optics: none - this tube has no optics inside
Internal diameter: the tube has an internal diameter of 30 mm, so that a projection eyepiece of exactly that diameter can be fitted inside

The trinocular heads this tube fits are used among others in the following microscopes:
- Leitz Wetzlar Orthoplan
- Leitz Wetzlar Diaplan
- Leitz Wetzlar Ergolux
- Leitz Wetzlar Dialux
- Leitz Wetzlar Laborlux
- Leitz Wetzlar SM-LUX
- Leitz Wetzlar Ortholux II
- Leitz Wetzlar Aristoplan
- Leitz Wetzlar HM-LUX

This is not a tube for one particular microscope model. A trino head can be mounted not only on the microscope it was sold with, so the correct assumption is that this is a standard tube for Leitz Wetzlar trinocular heads - and those can be used on most microscope models of this company.

The last photo in the gallery shows what this tube looks like with a 30 mm eyepiece fitted.

The "compatibility" section lists example microscopes this tube fits, although the list is not complete.

Description of this part for the microscope.

Wetzlar binocular head P/N 512821/20 (also written 512 821) - but exactly the same tube is used in other models of binocular and trinocular heads as well.

The same front panel design is found in, among others, the Leitz 512 923/20 and Leitz 512 815 trinocular heads - this tube with diopter adjustment will most likely fit those too.

Diameter of the eyepieces it takes: 23.2 mm.

In the Leitz bino 512821/20 both the left and the right tube have diopter adjustment. They are mechanically identical parts - there is no difference between the left and the right tube. They can be swapped.

Before you decide to use this tube in a Leitz Wetzlar head other than model 512 821/20, first compare the exact dimensions (the photos show a millimetre scale), and if you have any doubts, ask in internet groups and forums.

This is a service part for a microscope head - not for a specific microscope model. Such a head can be mounted on many Leitz Wetzlar microscope models (and even on microscopes from other makers), so no list of microscopes this tube fits can be given - it fits the head, and the user mounts the head wherever he wants.

In the "compatibility" section I list a few example Leitz Wetzlar microscope models that turn up on the second-hand market complete with the head this tube comes from - but this is definitely not a complete list. They include:
- Leitz Wetzlar Dialux 20 / Dialux 22 EB
- Leitz Wetzlar Laborlux K / Laborlux S
- Leitz Wetzlar Diaplan

On the last photos in the gallery you can see the Leitz Wetzlar 512821/20 binocular head taken apart, with an arrow pointing to which part this is and where it sits in the head. That makes it unambiguous to identify.

of:
- two brass carrier plates, each with a round seat for the eyepiece tube (it is to these plates that the tubes https://www.microscopeparts.eu/part/99928 are screwed)
- a central scissor lever made of plastic, with its fixing screw
- two pressure springs (one for each brass plate)

Turning the central lever moves both brass plates outwards symmetrically. It is exactly this constant work of the plastic central lever against the brass plates that wears the plastic lever out - and then it has to be replaced.

This mechanism was removed from the Leitz Wetzlar binocular head P/N 512821/20 (also written 512 821) - but exactly the same one is used in other models of binocular and trinocular heads as well.

The same front panel design is found in, among others, the Leitz 512 923/20 and Leitz 512 815 trinocular heads - this interpupillary mechanism will most likely fit those too.

From the outside this mechanism is covered by plastic covers - one on the right (https://www.microscopeparts.eu/part/99931) and a different one on the left (https://www.microscopeparts.eu/part/99930). These plastic covers carry a printed scale on which the interpupillary distance is read.

Before you decide to use this mechanism in a Leitz Wetzlar head other than model 512 821/20, first compare the exact dimensions (the photos show a millimetre scale), and if you have any doubts, ask in internet groups and forums.

internal interpupillary distance adjustment mechanism from the front (https://www.microscopeparts.eu/part/99929). The second, left cover is shaped differently and is a separate item (https://www.microscopeparts.eu/part/99930).

There is no printing on the right cover - the interpupillary scale is printed on the left cover. When the interpupillary distance is changed, the right cover covers or uncovers part of the left cover and with it part of the scale placed there - and this is how the interpupillary distance value is read.

The cover is made of plastic and is screwed with four screws directly to the brass carrier plate, to which the eyepiece tube (https://www.microscopeparts.eu/part/99928) is also fastened.
