# Description and specifications:
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?

# Examples of use
- very often this tube is dented and an eyepiece cannot be inserted
- very often the diopter adjustment ring becomes damaged and does not function
- if you want diopter adjustment on both eyepiece tubes and replace the simple tube with one equipped with an adjustment ring
- if you need a tube with precise worm adjustment for your own DIY purposes
