# 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:
Condensers

# Description and specifications:
Ring with a handle (lever) with a width of 6 mm for moving the iris diaphragm. The element contains grooves into which the protruding "pins" of the diaphragm blades are inserted.

This is an element for repair of a microscope condenser by Carl Zeiss Jena, model Abbe 1.2.
Please note that this is an element (component) for a microscope part (condenser), not for a specific microscope model.

The handle in this ring breaks very frequently, and then the iris diaphragm cannot be opened or closed and the condenser loses its functionality. In such a case, instead of replacing the entire condenser, it is enough to replace only this element - that is, to repair the condenser (recommendation: always repair - never throw away).

Note - over the years Carl Zeiss Jena produced the Abbe 1.2 condenser in different versions, and this ring is available in at least two variants:
- ring with a thickness of 2.5 mm and a handle width of 6 mm
- ring with a thickness of 2 mm and a handle width of 3.5 mm

Here I present and offer a ring with a thickness of 2.5 mm and a handle width of 6 mm. Be sure to check whether this is exactly the ring you need.

# Examples of use
- as a service part for replacement if the ring or the handle for moving the iris diaphragm has broken off, which is a common failure

# Removed from:

# Also compatible with the following microscopes:
