# Part name: Carl Zeiss Jena Jenaval / Jenapol microscope 6V 25W halogen lamp house with filter wheel # Original page URL: https://www.microscopeparts.eu/part/carl-zeiss-jena-jenaval-jenapol-microscope-6v-25w-halogen-lamp-house-with-filter-wheel-99693 # Part manufacturer: Carl Zeiss Jena # Full manufacturer name: VEB Carl Zeiss Jena DDR (former East Germany) # Other names of this manufacturer: - ausJena - aus Jena These are names commonly used to refer to this manufacturer of microscopes and microscope parts, even if they are not official. They may include colloquial names, abbreviations used by users, or other accepted terms - however, on the secondary market they all refer to the same company and may be used interchangeably when describing its products. # Belongs to category: Illuminators # Description and specifications: 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. # Examples of use - 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 # Removed from microscope: Carl Zeiss Jena Jenaval # Also compatible with the following microscopes: - Carl Zeiss Jena Jenaval - Carl Zeiss Jena Jenalumar - Carl Zeiss Jena Jenavert - Carl Zeiss Jena Jenapol # Names, descriptions, terms, and search contexts under which this part is searched. - Carl Zeiss Jena Jenaval microscope repair parts - Carl Zeiss Jena Jenaval / Jenapol microscope 6V 25W halogen lamp house with filter wheel - Carl Zeiss Jena Jenaval / Jenapol - mikroskopowy oświetlacz halogenowy 6V 25W z kołem filtrów - Zeiss Jenalumar Halogenlampe - Zeiss Jenavert Mikroskop Durchlicht Lampenhaus - Carl Zeiss Jena buy spare parts # Related URLs: - Markdown po polsku: https://www.serwismikroskopowy.pl/part/99693.md - Markdown auf Deutsch: https://www.mikroskopteile.de/part/99693.md - Gallery of all photos of this part: https://www.microscopeparts.eu/gallery/99693-carl-zeiss-jena-jenaval-jenapol-microscope-6v-25w-halogen-lamp-house-with-filter-wheel - Media manifest of this part (photos + videos, for AI/RAG): https://www.microscopeparts.eu/part/99693.media.md - Representative photo: https://www.microscopeparts.eu/photo/carl-zeiss-jena-jenaval-jenapol-microscope-6v-25w-halogen-lamp-house-with-filter-wheel-99693-2 - Representative video: https://www.microscopeparts.eu/play/99693-1 - Other parts from category Illuminators: https://www.microscopeparts.eu/illuminators - More Illuminators removed from microscope Carl Zeiss Jena Jenaval: https://www.microscopeparts.eu/illuminators/from/carl-zeiss-jena/jenaval - More Illuminators compatible with microscope Carl Zeiss Jena Jenaval: https://www.microscopeparts.eu/illuminators/for/carl-zeiss-jena/jenaval - More Illuminators removed from microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/illuminators/from/carl-zeiss-jena - More Illuminators compatible with microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/illuminators/for/carl-zeiss-jena # Important information: Database Description: Technical microscope parts database based on years of practical service experience.
