This is description of this part:
6V 25W halogen lamp house with a colour filter wheel for Carl Zeiss Jena Jenaval and similar microscopes.
Compatible with the following Carl Zeiss Jena microscope models:
1. Carl Zeiss Jena Jenaval
2. Carl Zeiss Jena Jenalumar
3. Carl Zeiss Jena Jenapol
4. Carl Zeiss Jena Jenavert
1. In Carl Zeiss Jena Jenaval microscopes, this lamp house is used as the transmitted-light illuminator.
2a. In Carl Zeiss Jena Jenalumar 50 microscopes (equipped with the small HBO 50 fluorescent lamp house, identical to the one used in Carl Zeiss Jena Jenamed Fluorescence microscopes), this lamp house serves as the transmitted-light source.
2b. Carl Zeiss Jena Jenalumar 250 microscopes are equipped with a large integrated lamp house. The unit offered here is therefore not compatible with this model.
3. In Carl Zeiss Jena Jenapol microscopes, this halogen lamp house is used both for transmitted light (mounted underneath) and for reflected light (mounted on the top). However, some Jenapol versions are equipped only for transmitted-light operation or only for reflected-light operation.
4. Carl Zeiss Jena Jenavert microscopes are normally equipped with a different lamp housing for reflected light. However, when the original unit is missing, users often modify a lamp house like the one offered here for DIY projects. In addition, if a Jenavert is equipped with a transmitted-light optical path, this lamp house is used as its transmitted-light source.
The lamp house is attached to the microscope using two long screws. Unusually—and this often makes them difficult to find—the screws are removed FROM THE FRONT of the microscope. Their heads are accessible through openings in the white sheet-metal side covers of the microscope body. These covers with the screw openings are shown in this database under item number 99692.
This lamp house contains a filter wheel with four positions for 32 mm diameter round filters. It is fitted with the same filter configuration originally supplied by Carl Zeiss Jena for the Jenaval model:
- one position is empty
- Carl Zeiss Jena C312 blue filter
- Carl Zeiss Jena D282 grey filter
- Carl Zeiss Jena V231 green filter
The filter wheel is an optional part of this lamp house. The example offered here is fitted with it, but it can be removed and the illuminator will still function perfectly as a light source.
Cast or injection-moulded ZnAl components manufactured by Carl Zeiss Jena carry identification numbers. The housing of this lamp house bears the number 2670 (full marking: 2670 Si10 CZ).
In the last photograph, an arrow indicates where this component is located in the microscope, making it easy to identify.
What is this part needed for?
- if your microscope is missing its lamp house
- if your lamp house is incomplete, damaged or in very poor condition
- if you need a second lamp house
- if you have a lamp house without a filter wheel and would like one fitted with colour filters
