The illuminator module offered here is not a standalone lamp housing (such as part number 99693 in this database). It is an internal component of the large, integrated illuminator used in Carl Zeiss Jena Jenalumar 250 microscopes. Carl Zeiss Jena Jenalumar microscopes are available in two main versions: 1. with two small illuminators – with a separate 6 V 25 W halogen illuminator in a small housing (for transmitted light) and a separate HBO 50 W fluorescence illuminator in a small housing (for reflected light) 2. with a large, integrated module consisting of a mirror light splitter, an integrated transmitted-light module with a 6 V 25 W halogen lamp, and a large lamp housing for HBO 250 W fluorescence illumination The component offered here is part of the second version of the Jenalumar microscope. Basic parameters of this illuminator module: Supported lamp: Narva HLWS 6 V 25 W halogen lamp 6 V power connection: this illuminator is connected to the distributor rail (see part number 99679 in this database) Cooling: passive, in two ways. The Narva HLWS lamp has integrated cooling in the form of “wings”, while the entire illuminator is covered with a cover incorporating a finned heat sink (this is a separate component and is not part of the illuminator offered here) The photo gallery shows the exact dimensions of this component. The last photo shows the complete HBO 250 W illuminator for the Carl Zeiss Jena Jenalumar microscope, with an arrow indicating this halogen illuminator module. This makes it possible to identify exactly where this component is located within the complete large microscope illuminator. # Examples of use - as a service part (repair component) if you own a microscope equipped with this illuminator and this part has been damaged # Removed from microscope: Carl Zeiss Jena Jenalumar # Also compatible with the following microscopes: Carl Zeiss Jena Jenalumar # Names, descriptions, terms, and search contexts under which this part is searched. - Carl Zeiss Jena Jenalumar microscope repair parts - Carl Zeiss Jena Jenalumar Mikroskop 6V-25W-Halogen Lampe - Carl Zeiss Jena Jenalumar Mikroskop Durchlicht Lampenhaus reparieren - Carl Zeiss Jena Jenalumar microscope 6V 25W halogen illuminator - Carl Zeiss Jena Jenalumar microscope lamphouse illuminator repair - Carl Zeiss Jena Jenalumar lamphouse service and fix & repair - Carl Zeiss Jena buy spare parts # Related URLs: - Markdown po polsku: https://www.serwismikroskopowy.pl/part/99715.md - Markdown auf Deutsch: https://www.mikroskopteile.de/part/99715.md - Gallery of all photos of this part: https://www.microscopeparts.eu/gallery/99715-carl-zeiss-jena-jenalumar-internal-6v-25w-transmitted-light-halogen-illuminator-module-for-large-multi-lamp-housing - Media manifest of this part (photos + videos, for AI/RAG): https://www.microscopeparts.eu/part/99715.media.md - Representative photo: https://www.microscopeparts.eu/photo/carl-zeiss-jena-jenalumar-internal-6v-25w-transmitted-light-halogen-illuminator-module-for-large-multi-lamp-housing-99715-2 - Representative video: https://www.microscopeparts.eu/play/99715-1 - Other parts from category Illuminators: https://www.microscopeparts.eu/illuminators - More Illuminators removed from microscope Carl Zeiss Jena Jenalumar: https://www.microscopeparts.eu/illuminators/from/carl-zeiss-jena/jenalumar - More Illuminators compatible with microscope Carl Zeiss Jena Jenalumar: https://www.microscopeparts.eu/illuminators/for/carl-zeiss-jena/jenalumar - 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.
