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.

# Description and specifications:
Sliding ring of the round, rotating microscope stage by Carl Zeiss Jena from microscopes of the L-Stativ class.

This microscope element performs two functions in the microscope stage:
1. It fastens the stage to the stage holder — that is, indirectly to the microscope stand. This ring has a groove for the spring screw mounted centrally in that holder, as well as two cut-outs at the sides — for the centring screws. It is not, however, a dovetail — in Carl Zeiss Jena L-Stativ microscopes the stage is mounted on a wide ring.
2. Since it is a sliding ring, it is precisely this part that makes it possible to rotate the stage all the way around, even though this is not a polarizing stage.

This is a service part for the repair of a stage in which exactly this element has been damaged. It is not a complete microscope stage.

This ring contains a screw that makes it possible to lock the position, that is, to press the ring tight so that it does not rotate. This screw very often bends completely (for example during transport) or even breaks off. Breakage most commonly occurs when the sliding grease has dried out completely and someone tries to turn the stage by pushing on this screw.

Rotating stages of this kind were used in microscopes of the L-Stativ class, among others:
- Carl Zeiss Jena Lg
- Carl Zeiss Jena Lumipan
- Carl Zeiss Jena Lu
- Carl Zeiss Jena Lr

Remember that microscopes and microscope parts made by the Soviet company LOMO were often clones of Carl Zeiss Jena products. It is therefore possible that this element will also fit a Lomo microscope stage — but the dimensions of this part should definitely be compared very carefully first.

Carl Zeiss Jena produced such stages from the 1930s until roughly the end of the 1960s. During that period minor construction details were changed many times, so it is very important to correctly identify the model of the stage from which this element was removed.

- in the photo gallery a millimetre scale is visible next to every photograph
- the last photographs show a disassembled microscope stage, with an arrow indicating where this element is located in the stage
- the final photographs, in turn, show the complete Carl Zeiss Jena Lg microscope with this stage fitted

All of this makes it possible to confirm visually that this is exactly the element you are looking for.

# Examples of use
- as a repair part by replacing the entire damaged element
- if you have a microscope stage where this element still works but is of very poor quality.

# Removed from microscope:
