# Part manufacturer:
Carl Zeiss Jena

# Full manufacturer name:
VEB Carl Zeiss Jena DDR (former East Germany)

# Other names of this manufacturer:

These are names commonly used to refer to this manufacturer of microscopes and microscope parts, even if they are not official. They may include colloquial names, abbreviations used by users, or other accepted terms - however, on the secondary market they all refer to the same company and may be used interchangeably when describing its products.

# Belongs to category:
Condenser holders (supports)

# Description and specifications:
Complete condenser vertical movement module for the Carl Zeiss Jena NU / NU-2 microscope.

This is a control knob with an integrated gear for condenser height adjustment together with a rack gear and the component on which the condenser holder is mounted.

Note - this module DOES NOT FIT Carl Zeiss Jena Nf and Carl Zeiss Jena Lu microscopes, even though the assemblies performing the same function in those microscopes look VERY similar.

In the last photos in the gallery, I use arrows to show exactly which microscope component is being offered and where it is located in the Carl Zeiss Jena NU-2 microscope.

# Examples of use
- as a service part
- for replacement when the plastic knob is broken
- if the rack has been damaged (this is a very common damage)
- for installation when the entire element is missing

# Removed from microscope:

# Also compatible with the following microscopes:
