Description of this part for the microscope.

was removed from a Carl Zeiss Jena Jenamed Cytology microscope. It will most likely also fit other models from the Jenamed series (e.g. Jenamed Variant, Jenamed Fluorescence, Jenamed-2, Jenamed Hematology).

It does not fit the Jenamed Histology model because the Carl Zeiss Jena Jenamed Histology microscope features a different type of condenser (a 'flip-out' type) by default. For this reason, the iris diaphragm is located slightly lower than in other models and is different.

To make sure whether this iris diaphragm will fit a specific Carl Zeiss Jena microscope from the Jenamed series, it is best to carefully check all dimensions based on the gallery photos or ask a question on a professional forum, e.g. https://www.mikroskopie-forum.de/

Mechanically, this diaphragm is mounted underneath the condenser. The entire diaphragm module is attached to the microscope body with four screws. It is not mechanically connected to the condenser - these are separate elements. The lever pin used to open / close the diaphragm protrudes through a special opening at the front of the microscope, making it possible to adjust the diaphragm opening. This opening is located in the cover of the filter wheel - here one can see further relationships between the individual elements of the light path.

Carl Zeiss Jena Jenamed microscopes do not have a field diaphragm.

Replacement of the aperture diaphragm module in a Carl Zeiss Jena Jenamed microscope may be necessary:
- when some of the iris diaphragm blades become damaged (bent or broken)
- when the lever used to open / close the diaphragm breaks off
- when the teeth of the gear wheel mounted in this module become damaged

Metal cast or injection-moulded microscope parts made by Carl Zeiss Jena have their own numbers. This part carries the number 2713 (full marking: Si10 CZ 2713).

Description of this part for the microscope.

This diaphragm DOES NOT FIT the following Carl Zeiss Jena microscopes:
- Jenamed 2
- Jenamed Variant
- Jenamed Cytology
- Jenamed Hematology
- Jenamed Fluorescence

Mechanically, this diaphragm is mounted below the condenser. The complete diaphragm module is attached to the microscope stand with two screws. It is not mechanically connected to the condenser - these are separate components. The lever (pin) used to open and close the diaphragm extends through a dedicated opening at the front of the microscope, allowing adjustment of the diaphragm opening. This opening is located in the cover of the filter wheel - illustrating further relationships between successive elements of the light path.

Carl Zeiss Jena Jenamed microscopes do not have a field diaphragm.

Replacement of the aperture diaphragm module in a Carl Zeiss Jena Jenamed Histology microscope may be necessary:
- when one or more iris diaphragm blades become damaged (bent or broken)
- when the lever used to open and close the diaphragm breaks off
- when the teeth of the gear wheel installed in this module become damaged

Metal cast or injection-moulded microscope parts manufactured by Carl Zeiss Jena carry their own part numbers. This part bears number 2714 (full marking: Si10 CZ 2714). The iris diaphragm module used in the other Carl Zeiss Jena Jenamed microscope models bears part number Si10 CZ 2713.
