Steindorff Berlin microscope - 45 mm eyepiece tubus with diopter adjustment ring

The name of this microscope part.

Steindorff Berlin microscope - 45 mm eyepiece tubus with diopter adjustment ring

Description of this part for the microscope.

Eyepiece tube with a maximum length of 45 mm for the microscope head of Steindorff Berlin.

This is a tube with an assembled diopter adjustment ring that allows ...

correction of vision defect in one eye and proper image focus adjustment.

Basic parameters:
- Type: tube with diopter correction ring
- Supported eyepiece diameter: 23.2 mm
- Maximum length: 45 mm
- Color: steel

Steindorff Berlin produced two main types of binocular microscope heads:
- with straight tubes
- with diverging tubes in the "Y" standard.
In each of them, eyepiece tubes with a length (maximum length measured with the diopter adjustment ring fully unscrewed): 45 mm or 50 mm could be installed.

I was not able to find information what this depended on:
- maybe some tubes were older and others newer
- maybe some were designed for TL=170 mm and others for TL=160 mm
- maybe some matched objectives FL=37 mm and others FL=45 mm

This element may answer the following issues related to the Steindorff Berlin microscope:
- Is it possible to have diopter adjustment on both eyepieces?
- How to straighten a bent eyepiece tube?
- Diopter adjustment does not work - how to replace the grease?

Leitz Wetzlar Heine microscope condenser 39,5 mm | Carl Zeiss Jena and PZO Biolar compatible

The name of this microscope part.

Leitz Wetzlar Heine microscope condenser 39,5 mm | Carl Zeiss Jena and PZO Biolar compatible

Description of this part for the microscope.

Heine microscope condenser made by Leitz Wetzlar.

A Heine condenser allows smooth, continuous switching between different observation techniques:
- ...

bright field
- dark field
- oblique illumination
- phase contrast

It can work with phase objectives of different magnifications and from different manufacturers (it is sufficient to manually adjust the ring diameter).

Basic parameters:
Manufacturer: Leitz Wetzlar
Model: Heine condenser
Mounting diameter: 39.5 mm
Numerical aperture N.A.: variable, up to 1.4

This Heine condenser was designed for microscopes with a condenser holder in the form of a circular clamp (e.g. Leitz SM microscopes). It is not a condenser that slides into mounting rails (as found, for example, in the Leitz Orthoplan microscope).

This condenser fits microscopes from many manufacturers (e.g. PZO, Steindorff Berlin, Zeiss, Carl Zeiss Jena, Leitz, Kremp Wetzlar, Will Wetzlar and many others) equipped with a 39.5 mm condenser holder.
