Focal length: 37 mm

At that time (most likely in the 1950s) the objectives mounted in microscopes from different manufacturers looked very similar. Many microscope manufacturers ordered objectives from large optics manufacturers (e.g. Leitz Wetzlar) and then only engraved their own names on them.
Because of this, these objectives can be used with microscopes from many other manufacturers.

This objective was removed from a Leitz Dialux microscope, but it is compatible with most Leitz Wetzlar microscopes manufactured approximately before 1980 (SM, SM-Lux, Dialux, Ortholux, Orthoplan, etc.).

Some useful information about Leitz Wetzlar objectives with TL=170 mm and FL=37 mm:
- most Leitz microscopes manufactured approximately before 1980 support both 160 mm and 170 mm tube length objectives
- many Leitz microscopes support both 37 mm and 45 mm parfocal length objectives
- by adding an RMS-8mm adapter, such an objective obtains a parfocal length of 45 mm. Leitz manufactured such adapters under the name "Plezzy" - however, many users make their own versions from metal or by using 3D printers

any microscope from any manufacturer that allows the use of eyepieces with a mounting diameter of 23.2 mm.

The company "Dr. G. Schuchardt Göttingen" did not and does not produce microscopes. Previously, it primarily sold microscopes manufactured by Hertel & Reuss and Will Wetzlar under its own brand.

from a Leitz Dialux microscope. In the last photo in the gallery you can see the microscope stage from which it was removed. However, the manufacturer fitted the same type of mechanical XY microscope stage to many other Leitz microscope models, so this specimen holder is also compatible with models other than the Leitz Dialux.

When determining compatibility and whether this specimen holder can be mounted on a particular mechanical XY microscope stage, the following dimensions are critical:
- distance between the two side locating pins: 81 mm measured from the outer edge of one pin to the outer edge of the other pin
- locating pin diameter: 3 mm each
- therefore, the centre-to-centre distance between the locating pins is 78 mm
- diameter of the central mounting screw: 4 mm
- position of the mounting screw: centred between the two locating pins

If the spacing of the locating pins matches, this specimen holder can also be mounted on microscope stages made by other manufacturers.

Leitz Wetzlar produced specimen holders with fixed stage clips as well as versions with a spring-loaded stage clip. Here I am showing and offering the spring-loaded version.

On the used market and in technical documentation, this microscope part is described using a variety of names. Common terms include:
- specimen holder
- microscope stage specimen holder
- mechanical stage specimen holder
- slide holder
- microscope slide holder
- microscope slide clamp
- spring-loaded specimen holder
- spring-loaded slide holder
- spring-loaded stage clip
- specimen clamp
- specimen carrier
- mechanical stage carrier
- XY stage specimen holder
- specimen holder for mechanical XY microscope stage
- stage holder
- stage clip assembly

The photographs in the gallery show the exact dimensions of the microscope part offered here. In addition, the last photograph includes an arrow indicating exactly which microscope part is being described and where it is mounted on the mechanical XY microscope stage, making identification straightforward. The accompanying video demonstrates the operation of the spring-loaded stage clip.

allowing precise movement of the specimen in both the X and Y axes of the stage plane. The manipulator consists of two coaxial knobs, two independent drive shafts and the fixing elements that attach it to the stage mechanism.

This particular manipulator was removed from a Leitz Dialux microscope. The last photograph in the gallery shows the entire microscope stage from which it was dismounted. The manufacturer also used the same or very similar stages in many other Leitz Wetzlar microscope models, which is why the manipulator may also be compatible with other models from this company.

On the second-hand market and in service documentation one encounters many names referring to this assembly. The most commonly used terms include, among others:
- stage manipulator
- XY stage manipulator
- mechanical stage drive
- stage control knobs
- specimen mover
- coaxial stage drive
- stage drive assembly
- mechanical stage control
- manual XY stage drive
- stage actuator mechanism

Such manipulators very often suffer mechanical damage during transport of the microscope. Because they protrude beyond the outline of the stand, it is precisely they that absorb the impact energy first - in the event of a fall or improper packaging of the instrument.

In many cases it is not the entire manipulator that is damaged, but only one of its components. Most often these are the knobs, the drive shafts, the coaxial sleeves or the fixing elements. For this reason, this database also contains all the most important constituent parts of this (and other) manipulators, offered separately as service elements.

Damage to the manipulator does not make further work with the microscope impossible. The specimen can be moved by hand, or a simple specimen holder without an XY movement mechanism can be fitted. Such a solution works well at low magnifications; however, when working with objectives of magnifications greater than 40x (e.g. 60x, 63x, 80x or 100x), precise manual movement of the specimen becomes very difficult. At total magnifications exceeding about 400x, even a slight movement of the hand shifts the image by a considerable distance within the field of view. The mechanical manipulator enables very smooth, controlled and repeatable movement of the specimen in both axes, which is particularly important during observation with oil immersion and when producing photographic documentation.

The photographs in the gallery show the exact dimensions of the complete manipulator. The last photograph presents the entire microscope stage together with an arrow indicating the mounting location of this element, which makes it possible to identify the offered part unambiguously.

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.

Because this is important, I will write it again: this is a single eyepiece, not a pair of eyepieces.

This is a solution for people who:
- either have a pair of these eyepieces, but one of them needs to be replaced
- or have a microscope with a monocular head

For Will Wetzlar microscopes, eyepieces from practically any manufacturer can be used, provided that they are designed for a finite tube length system and have a mounting diameter of 23.2 mm. However, many users appreciate having original parts.

This eyepiece also works the other way around - it fits almost any microscope from any manufacturer that allows the use of eyepieces with a mounting diameter of 23.2 mm. Users of microscopes from many manufacturers are happy to choose German eyepieces because of their high quality. I have included some examples in the "compatibility" section, but this is definitely not a complete list.

Parfocal length: 37 mm
Tube length: 170 mm
Cover glass: yes, 0.17 mm thick
Immersion: no - this is a dry objective
Thread: RMS

This is a so-called "short barrel" objective with a parfocal length of 37 mm. It is very often mounted on an 8 mm extension, which allows it to be used in microscopes that require 45 mm (long barrel) objectives. Professional adapters with protective optics, metal adapters and popular DIY 3D-printed adapters all work well for this.

The company "Dr. G. Schuchardt Göttingen" did not manufacture microscopes and does not manufacture them today. In the past it mainly sold microscopes made by Hertel & Reuss and Will Wetzlar under its own brand, today its products are imported from China.

This objective fits virtually any microscope from any manufacturer, as long as it has an RMS thread and accepts objectives for TL = 170 mm with a parfocal length of 33 or 37 mm (or 45 mm when a suitable adapter is used). Several example microscopes are listed in the "Compatibility" section, but the list is not complete.

Because it works without a cover glass and has a high numerical aperture N.A., this objective can be attractive for macro photographers. It allows projection directly onto the camera sensor - without any intermediate optics.

This objective was removed from a Leitz SM microscope, but it fits most Leitz Wetzlar microscopes made before roughly 1980 (SM, SM-D, SM-Lux, Dialux, Ortholux, Orthoplan, etc.).

Some useful information about Leitz Wetzlar objectives with TL=170 mm and 37 mm parfocal length:
- most Leitz microscopes made before roughly 1980 accept objectives for both 160 mm and 170 mm tube length
- many Leitz microscopes accept objectives with both 37 mm and 45 mm parfocal length
- with an 8 mm RMS extension adapter, such an objective gets a parfocal length of 45 mm. Leitz made such adapters under the name "Plezy" - but many users make their own, from metal or on 3D printers

Like a large share of microscope objectives made in Germany in the 1960s and 1970s, this objective has a 37 mm parfocal length and a 170 mm tube length. For this reason it is often used as a replacement objective for other German microscopes, e.g.:
- Steindorff Berlin
- Kremp Wetzlar
- Hertel & Reuss
- Steinmar Berlin
- CBS Beck Kassel
- ROW Rathenow

This objective fits practically any microscope from any manufacturer, as long as it has an RMS thread and accepts objectives with TL=170 mm and a parfocal length of 33 / 37 mm (or 45 mm with a suitable adapter). Some examples of such microscopes are listed in the "compatibility" section, but this list is not complete.

of view number: 12
Mounting diameter: 23.2 mm
Designation: PK = plan compensating - recommended for work with planachromatic objectives, but they also work without any trouble with achromats or apochromats

Because of their very high quality they are often used on microscopes from other manufacturers as well, especially when Carl Zeiss Jena Planachromat objectives are mounted in them. The "compatibility" section lists a long series of microscopes these eyepieces fit - but that list is definitely not complete.

Important: these eyepieces work both on microscopes with a finite tube length (160 mm, for example) and on microscopes with infinity optics. That means you can use them on the Carl Zeiss Jena Amplival microscope just as well as on the Carl Zeiss Jena NU-2 microscope.

A note - eyepieces with such a strong magnification are in my opinion better suited to a quick look than to permanent work. I write "in my opinion" on purpose, because this comes from using them and not from the manufacturer's description.
A 16x eyepiece magnification should be treated as a zoom that brings out no additional detail (the resolution is not increased). This matters for example with heads that have their own extra magnification (such as Carl Zeiss Jena heads with a built-in 1.5x or 1.6x factor) - working with a 100x oil immersion objective you then theoretically get 100*1.5*16 = 2400x, while physics does not allow light from the visible range to be usefully magnified for the human eye beyond roughly 1250x - so this is what is called empty magnification.
