This is description of this part:
Transmitted-light path assembly with a frosted filter for Carl Zeiss Jena Jenaval, Jenalumar and similar microscopes.
Compatible with the following Carl Zeiss Jena microscope models:
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenapol
- can also be installed in a Carl Zeiss Jena Jenavert microscope to add transmitted-light capability
This component is located inside the microscope base. It receives the light beam from the illuminator, homogenises it (by diffusing the image of the lamp filament using a frosted filter acting as a diffuser) and then properly collimates it using a collimating lens. The prepared light beam then passes through another lens before reaching the right-angle mirror (sold as a separate component).
This part is well known on the secondary market among hobbyists and engineers building their own DIY optical projects, where it is frequently reused.
Interestingly, microscope versions intended exclusively for reflected-light operation (for example, the basic versions of the Carl Zeiss Jena Jenavert) do not contain this component because they do not have a transmitted-light optical path. However, both the microscope arm and the microscope base are identical to those used in transmitted-light models. This makes it possible to upgrade such an EPI microscope for transmitted-light operation by installing the complete lower transmitted-light optical path. The component offered here is one of the parts required for this conversion.
In the last photograph, an arrow indicates where this component is located inside the microscope, making it easy to identify.
What is this part needed for?
- as a service element for whole-module replacement
- if you need such a collimator with a frosted diffuser for your own DIY project
