Meopta RU2 / DRU-3 polarizing microscope monocular eyepiece head with adjustable draw tube with 150 mm - 190 - photo gallery

This is description of this part:

Monocular eyepiece head with an adjustable draw tube providing a variable tube length from 150 mm to 190 mm for the Meopta RU2 / DRU-3 polarizing microscope.

This is a dedicated eyepiece head for a polarizing microscope. It features:
- an adjustable draw tube with an engraved 150 mm – 190 mm scale
- a groove at the top of the eyepiece tube for locking the polarizing eyepiece in a fixed rotational position
- a locating pin (threaded pin) in the dovetail mount securing the head to the microscope body, allowing the head to be locked in a fixed position

Basic dimensions and specifications:
Compatible eyepiece diameter: 23.2 mm
Microscope body mounting type: dovetail
Dovetail diameter: 40.5 mm (compatible with, among others, Carl Zeiss Jena and Lomo microscopes)
TL scale range: 150 mm to 190 mm

The adjustable draw tube allows the use of microscope objectives corrected for different tube lengths (TL), for example:
- common polarizing objectives with TL = 160 mm (e.g. Carl Zeiss Jena and most other manufacturers)
- commonly encountered objectives with TL = 170 mm (e.g. older Leitz Wetzlar or Meopta)
- polarizing objectives with TL = 190 mm (e.g. Lomo)

Important: When calculating the total tube length (TL), the thickness of the mounting flange of the microscope eyepiece must also be taken into account.
