This is description of this part:
Blanking plug that is screwed into the place of the illumination collector located in the microscope base (stand base) of Carl Zeiss Jena Ergaval / Amplival microscopes and related models.
This element is used when transmitted light is temporarily not needed. The illuminator itself does not need to be removed - instead, the light output should simply be completely blocked, and this light output is the collector lens itself. This collector lens is located inside the microscope base, above the angle mirror and below the condenser.
When can there be a need to completely block transmitted light? Most often when:
- a microscope with DIA illumination (transmitted light) and EPI illumination (reflected light) is available, but temporarily only reflected light operation is needed
- a microscope previously working with transmitted light (for example Carl Zeiss Jena Amplival) is being converted into a microscope intended to work permanently only with reflected light (for example converting an Amplival into a Vertival)
- for example a Fluoval microscope is used and it is undesirable that "the lower light is visible"
This element fits the following microscopes:
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival
- Carl Zeiss Jena Epival
- Carl Zeiss Jena Vertival
- Carl Zeiss Jena Interphako
- Carl Zeiss Jena Fluoval
- Carl Zeiss Jena Docuval
The photo gallery contains detailed photos of this element from different sides, while the video (in the video gallery) shows exactly how this blanking plug is used and where it is mounted.
What is this part needed for?
