# Part manufacturer:
Carl Zeiss Jena

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

# Other names of this manufacturer:
- ausJena
- aus Jena
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:
Focusing blocks

# Description and specifications:
Complete fine focus block (micro movement / micro focusing) for the Carl Zeiss Jena Lg microscope.

The set consists of:
- brass block with the manufacturer logo
- knobs operating the internal mechanism
- gear assembly forming the fine focus mechanism (it can be removed because it is a replaceable microscope element)

The entire block fits the Carl Zeiss Jena Lg microscope (from the L-Stativ group), however the fine focus mechanism inside can be unscrewed and as far as I know (to the best of my knowledge) it also fits the microscopes:
- Carl Zeiss Jena Lr
- Carl Zeiss Jena Lu
- Carl Zeiss Jena Lumipan

# Examples of use
- as a service part in the form of replacing the entire block
- if you need the fine focus mechanism located inside - to use it in another microscope
- if you need a precise vertical or horizontal movement mechanism, for example for super macro photography

# Removed from microscope:
Carl Zeiss Jena Lg

# Also compatible with the following microscopes:
- Carl Zeiss Jena Lg
- Carl Zeiss Jena Lr
- Carl Zeiss Jena Lu
- Carl Zeiss Jena Lumipan
