# Description and specifications:
6-position objective nosepiece for Carl Zeiss Jena Jenalumar and Jenaval microscopes.

Basic specifications of this objective nosepiece:
- Number of objective positions: 6
- Thread: M25
- Mounting method: screw-mounted to the intermediate bracket (nosepiece holder), between the nosepiece and the microscope body

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 Jenalumar microscope is different from the one used in the Carl Zeiss Jena Jenaval microscope, but both holders have exactly the same objective revolver attached to them.

This offer includes only the objective turret, without the mounting bracket.

The gallery contains photographs of a Carl Zeiss Jena Jenalumar microscope arm, with the objective nosepiece indicated by an arrow to clearly show its location. It also includes photographs of the complete module consisting of the objective revolver and its holder for the Jenalumar microscope, making it clear how these two components are connected.

This database also contains, under item number 99388, the complete objective nosepiece module with its holder for the Carl Zeiss Jena Jenaval microscope.
