Steindorff Berlin Model C.Y.N. 10/0,30 microscope objective 10x | Leitz Wetzlar SM compatible

The name of this microscope part.

Steindorff Berlin Model C.Y.N. 10/0,30 microscope objective 10x | Leitz Wetzlar SM compatible

Description of this part for the microscope.

Achromatic 10x microscope objective by Steindorff Berlin.

Manufacturer: Steindorff Berlin
Model: 10/0.30
Magnification: 10x
Correction: ...

achromatic
Numerical aperture N.A.: 0.30
Tube length: 170 mm
Parfocal length: 37 mm
Cover glass: yes, 0.17 mm thick
Immersion: no (dry objective)
Thread: RMS

The Steindorff 10x objective is also suitable for macro photography, as it does not require a cover glass and allows direct projection onto the camera sensor without intermediate optics.

This is a so-called "short objective", with a parfocal length of 37 mm. It is particularly common to mount this objective on an 8 mm extension, which makes it possible to use the objective in microscopes requiring objectives with a parfocal length of 45 mm. Both professional adapters with protective optics and metal adapters, as well as popular DIY solutions made with a 3D printer, work well for this purpose.

Like a large proportion of microscope objectives manufactured in Germany in the 1960s and 1970s, this objective has a parfocal length of 37 mm and a tube length of 170 mm. This means that it is often used as a replacement objective for other German microscopes, such as:
- Leitz Wetzlar
- Kremp Wetzlar
- Hertel & Reuss
- Steinmar Berlin
- CBS Beck Kassel
- ROW Rathenow

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

Steindorff Berlin Ph 40/0.65 Phase Contrast 40x microscope objective

The name of this microscope part.

Steindorff Berlin Ph 40/0.65 Phase Contrast 40x microscope objective

Description of this part for the microscope.

Achromatic Steindorff Berlin microscope objective with 40x magnification for brightfield and phase contrast.

Manufacturer: Steindorff Berlin
Model: Ph 40/0, ...

65
Magnification: 40x
Correction: achromatic
Numerical aperture N.A.: 0.65
Tube length: 170 mm
Parfocal length: 37 mm
Cover glass: yes, 0.17 mm thick
Immersion: no (dry objective)
Thread: RMS
Phase contrast: yes - the objective has a built-in phase ring

Older Steindorff Berlin microscope models had a phase contrast condenser consisting of a standard brightfield condenser with a swing-out set of annular stops mounted below it (see here: https://www.facebook.com/groups/136833493390496/posts/1722963914777438/). It is not certain that this objective will match that condenser, because the annular stop there is marked 45x, while the objective offered here is 40x.

Only the Steindorff Berlin turret condenser (see here: https://www.facebook.com/groups/136833493390496/posts/1746808269059669/) has a 40x annular stop, and this objective is compatible with it.

I am not aware of Steindorff Berlin "Ph" objectives working with phase contrast condensers from other manufacturers. Please note: "not aware" does not mean they do not fit - but it is safer to assume they do not. In other words, you should assume that this objective will form a working set only with a Steindorff Berlin phase contrast condenser.
