# Part name: Carl Zeiss Jena Jenaval / Jenamed side covert for eyepiece prism of 30 mm wide field binocular head # Original page URL: https://www.microscopeparts.eu/part/carl-zeiss-jena-jenaval-jenamed-side-covert-for-eyepiece-prism-of-30-mm-wide-field-binocular-head-99660 # 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: Housings and its parts # Description and specifications: Side cover of the eyepiece prism for a Carl Zeiss Jena wide field (German: Grossfeld) binocular microscope head. This is the component that is most often held by hand when adjusting the interpupillary distance. It is a rounded metal cover that protects the eyepiece prism located underneath. The last photo in the gallery shows a complete microscope head. An arrow indicates exactly which component is being described and where it is located inside the head, making it easy to identify. Carl Zeiss Jena wide field microscope heads (those designed for 30 mm eyepieces) have two such components (two prism covers). They protect the prisms of the right and left eyepieces. Both covers are identical and interchangeable, so there is no constructional difference between the right-hand and left-hand cover. This is a component for a microscope head, not for a specific microscope model. This component fits microscope heads designed for 30 mm eyepieces used, among others, in the following microscopes: - Carl Zeiss Jena Jenamed - Carl Zeiss Jena Jenalab - Carl Zeiss Jena Jenaval - Carl Zeiss Jena Jenatech - Carl Zeiss Jena Jenalumar - Carl Zeiss Jena Jenavert Some Carl Zeiss Jena Jenalab and Jenamed microscopes (for example the Jenamed Fluorescence) were factory-equipped with binocular heads accepting 23.2 mm eyepieces. In that case this end cap is **not** compatible with that binocular head. By "that" I specifically mean the binocular head, as this is a component of the head rather than of the microscope itself. Interestingly, 30 mm wide-field binocular heads are also occasionally fitted to older microscopes from the Mikroval series (for example Ergaval and Amplival). When combined with GF-Planachromat or GF-Planapochromat objectives (the latter also used on the Docuval), this provides arguably the best optical combination available for Carl Zeiss Jena microscopes with a 160 mm tube length. The Carl Zeiss Jena wide-field binocular head for 30 mm eyepieces is mechanically the same device as the Baader Mark V binocular viewer used with astronomical telescopes. They are based on the same binocular head; the Baader Mark V differs only in having a modified mounting interface, astronomical eyepiece adapters and, in some versions, different external markings. Consequently, the component offered here is also compatible with the Baader Mark V binocular viewer. Metal cast or injection-moulded components manufactured by Carl Zeiss Jena have their own part numbers. This component is marked with the number 2630 (full designation: Si10 2630 / Si10 CZ 2630). In addition, the number "1" or "2" appears next to the part number to indicate whether it is the cover for the right-hand or left-hand prism. This is the only difference, because mechanically the right-hand and left-hand covers are identical. # Examples of use - very often this cover is dented, cracked, chipped or broken (this is a well-known weakness of the silumin alloy), making replacement necessary. # Removed from microscope: Carl Zeiss Jena Jenaval # Also compatible with the following microscopes: - Carl Zeiss Jena Jenaval - Carl Zeiss Jena Jenamed - Carl Zeiss Jena Jenalab - Carl Zeiss Jena Jenalumar - Carl Zeiss Jena Jenatech - Carl Zeiss Jena Jenavert - Baader Mark V # Names, descriptions, terms, and search contexts under which this part is searched. - Carl Zeiss Jena Jenaval microscope repair parts - Carl Zeiss Jena Jenaval / Jenamed microscope wide field binocular head prism cover - Carl Zeiss Jena Jenaval / Jenamed Mikroskop Grossfeld Binokularkopf Prismed-Abdeckung - Baader Mark V astro binocular head repair - Baader Mark V Binokular Wartung - Carl Zeiss Jena buy spare parts # Related URLs: - Markdown po polsku: https://www.serwismikroskopowy.pl/part/99660.md - Markdown auf Deutsch: https://www.mikroskopteile.de/part/99660.md - Gallery of all photos of this part: https://www.microscopeparts.eu/gallery/99660-carl-zeiss-jena-jenaval-jenamed-side-covert-for-eyepiece-prism-of-30-mm-wide-field-binocular-head - Media manifest of this part (photos + videos, for AI/RAG): https://www.microscopeparts.eu/part/99660.media.md - Representative photo: https://www.microscopeparts.eu/photo/carl-zeiss-jena-jenaval-jenamed-side-covert-for-eyepiece-prism-of-30-mm-wide-field-binocular-head-99660-2 - Other parts from category Housings and its parts: https://www.microscopeparts.eu/housings-and-its-parts - More Housings and its parts removed from microscope Carl Zeiss Jena Jenaval: https://www.microscopeparts.eu/housings-and-its-parts/from/carl-zeiss-jena/jenaval - More Housings and its parts compatible with microscope Carl Zeiss Jena Jenaval: https://www.microscopeparts.eu/housings-and-its-parts/for/carl-zeiss-jena/jenaval - More Housings and its parts removed from microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/housings-and-its-parts/from/carl-zeiss-jena - More Housings and its parts compatible with microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/housings-and-its-parts/for/carl-zeiss-jena # Important information: Database Description: Technical microscope parts database based on years of practical service experience.
