# Part name: Carl Zeiss Jena Jenalumar / Jenavert microscope double filter wheel | Jenaval compatible # Original page URL: https://www.microscopeparts.eu/part/carl-zeiss-jena-jenalumar-jenavert-microscope-double-filter-wheel-jenaval-compatible-99932 # 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: Filters # Description and specifications: Empty double filter wheel for the illuminators (Lampenhaus) of Carl Zeiss Jena Jenalumar microscopes and similar models. This part fits the lamphouses used on the following microscopes: - Carl Zeiss Jena Jenaval - Carl Zeiss Jena Jenalumar - Carl Zeiss Jena Jenapol - Carl Zeiss Jena Jenavert Each of these discs has 5 seats that take filters of 32 mm diameter. The filters are locked in place by a springy retaining ring (a so-called Sprengring) so that they cannot fall out. The set offered here comes with 10 such rings. Since each wheel can be loaded with five filters, the total number of possible combinations is 25. At the moment these filter seats are empty. Neither wheel has any filters fitted - you are free to load them with whatever filters you like. This two-wheel module fits halogen, HBO and XBO lamphouses. Parts made by Carl Zeiss Jena, cast or injection moulded from ZnAl alloy, carry their own numbers by which they can be identified. This double filter revolver module consists of 3 cast components: - 2672 Si10 CZ - the frame carrying both wheels. It is at the same time the outer cover plate with which the whole module is screwed onto the lamphouse - 2957 Si10 CZ - the thick filter wheel - and note: the thin filter wheel also carries the number 2957 Si10 CZ, which is unusual for this manufacturer - that two parts differing in dimensions should share the same number This double filter wheel is sometimes also called: - double filter holder - double filter turret - dual filter carrier - double filter slider - double filter changer Here https://www.microscopeparts.eu/part/99693 you can see what a complete 6V 25W halogen illuminator looks like with a single filter wheel fitted. The double set offered here fits such an illuminator among others, so the single filter wheel from the illuminator of a Carl Zeiss Jena Jenaval microscope can, for example, be replaced by the double one. # Examples of use - if you own a Carl Zeiss Jena microscope with an illuminator whose filter wheel is missing - if your lamphouse holds only a single filter wheel and you want to replace it with a double one - if there is already a filter wheel in your lamphouse, but you own so many loose filters that you want to load another changer with them and swap whole filter sets quickly # Removed from microscope: Carl Zeiss Jena Jenalumar # 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 Jenalumar microscope repair parts - Filterrad Lampenhaus Carl Zeiss Jena Jenaval fehlt - Doppel-Filterrad Jenalumar nachrüsten - filter wheel for Carl Zeiss Jena Jenapol lamphouse - double filter wheel for 32mm microscope filters - Filterhalter 32 mm Durchmesser Zeiss Jena Lampengehäuse - 32mm filter holder microscope illuminator replacement - Sprengring für Filter im Filterrad Mikroskop - retaining ring for 32mm microscope filter - Filterrevolver Jenavert HBO XBO Lampenhaus - filter changer for HBO XBO lamphouse Zeiss Jena - 2957 Si10 CZ Filterrad Zeiss Jena - 2672 Si10 CZ Zeiss Jena Gussteil Nummer - Filterrad gesprungen Zeiss Jena Lampenhaus - Filterrad klemmt Jenaval Lampenhaus - filter wheel cracked Zeiss Jena lamphouse - filter wheel stuck microscope illuminator - Zeiss Jena Jenamed 2 Lampenhaus Filterrad - Zeiss Jena Jenapol-U Filterscheibe Beleuchtung - Carl Zeiss Jena Jenalumar Lampenhaus aufarbeiten - restoring an antique Carl Zeiss Jena Jenaval illuminator - DIY Filtersatz im Lampenhaus wechseln Zeiss Jena - Halogenlampenhaus 6V 25W Zeiss Jena Filterrad - dvojitý filtrový kotouč do osvětlovače Carl Zeiss Jena - rueda de filtros doble para microscopio Carl Zeiss Jena - portafiltros doble microscopio Jenaval 32 mm - ruota portafiltri doppia microscopio Carl Zeiss Jena - cambia filtri lampada microscopio Jenalumar - podwójne koło filtrów do oświetlacza mikroskopu Carl Zeiss Jena - Carl Zeiss Jena buy spare parts # Related URLs: - Markdown po polsku: https://www.serwismikroskopowy.pl/part/99932.md - Markdown auf Deutsch: https://www.mikroskopteile.de/part/99932.md - Gallery of all photos of this part: https://www.microscopeparts.eu/gallery/99932-carl-zeiss-jena-jenalumar-jenavert-microscope-double-filter-wheel-jenaval-compatible - Media manifest of this part (photos + videos, for AI/RAG): https://www.microscopeparts.eu/part/99932.media.md - Representative photo: https://www.microscopeparts.eu/photo/carl-zeiss-jena-jenalumar-jenavert-microscope-double-filter-wheel-jenaval-compatible-99932-2 - Representative video: https://www.microscopeparts.eu/play/99932-1 - Other parts from category Filters: https://www.microscopeparts.eu/filters - More Filters removed from microscope Carl Zeiss Jena Jenalumar: https://www.microscopeparts.eu/filters/from/carl-zeiss-jena/jenalumar - More Filters compatible with microscope Carl Zeiss Jena Jenalumar: https://www.microscopeparts.eu/filters/for/carl-zeiss-jena/jenalumar - More Filters removed from microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/filters/from/carl-zeiss-jena - More Filters compatible with microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/filters/for/carl-zeiss-jena # Important information: Database Description: Technical microscope parts database based on years of practical service experience.
