# Belongs to category:
Iris diaphragms

# Description and specifications:
Aperture iris diaphragm for the Carl Zeiss Jena panchromatic microscope condenser used in Amplival-class microscopes.

Basic data:
Manufacturer: Carl Zeiss Jena
Version: grey version, removed from a Carl Zeiss Jena Amplival microscope
Mounting method: aperture diaphragm in the form of a detachable module
Centerable: yes

This iris diaphragm module is mechanically mounted to the bottom of the panchromatic condenser.

In Carl Zeiss Jena panchromatic condensers, the diaphragm is designed as a detachable module because it can be removed and replaced, for example, with a phase contrast module or a polarization module. Precisely because this microscope part can be detached, it is often missing from condensers available on the secondary market - over the years it simply gets lost.

Interestingly, this microscope part is very often modified. When users do not have a phase contrast module or a polarization module, they frequently insert polarizing film or custom-made phase rings into the aperture diaphragm module and obtain the functionality they need through DIY modifications.

This module can also solve a common problem found in Carl Zeiss Jena Amplival microscopes, namely damaged diaphragm blades in the condenser.

# Examples of use
- if you own a panchromatic condenser without an aperture diaphragm
- if you already own a panchromatic condenser with an aperture diaphragm, but the diaphragm is damaged or of very poor quality - which is very common
- if you need this microscope part for your own DIY projects
