# Description and specifications:
Holder for mounting the objective nosepiece to the microscope arm of a Carl Zeiss Jena Jenaval microscope.

This component is located between the rotating objective nosepiece and the microscope arm of the Carl Zeiss Jena Jenaval microscope.

The complete assembly (objective revolver ↔ holder ↔ microscope arm) is connected together with screws.

The complete objective nosepiece module for Carl Zeiss Jena Jenalumar or Jenaval microscopes consists of:
- the objective revolver (also called the objective nosepiece, nosepiece disc or objective turret)
- the intermediate mounting bracket (nosepiece holder).

In both microscope models, the Carl Zeiss Jena Jenalumar and the Carl Zeiss Jena Jenaval, the first component—the objective revolver—is identical and interchangeable between the two models. Only the intermediate mounting bracket differs, as it attaches the revolver to the microscope arm. In other words, the nosepiece holder used in the Carl Zeiss Jena Jenaval microscope is different from the one used in the Carl Zeiss Jena Jenalumar microscope, but both holders have exactly the same objective revolvers attached to them.

This listing includes only the intermediate holder for the Carl Zeiss Jena Jenaval model, without the objective nosepiece.

Cast or injection-moulded ZnAl components manufactured by Carl Zeiss Jena carry identification numbers that allow them to be identified. This component bears the number 2643 (full marking: Si10 CZ 2643).
