# Part name: Carl Zeiss Jena Jenaval / Jenamed microscope central, round end cap with interpillary distance scale for 30 mm wide field binocular head # Original page URL: https://www.microscopeparts.eu/part/carl-zeiss-jena-jenaval-jenamed-microscope-central-round-end-cap-with-interpillary-distance-scale-for-30-mm-wide-field-99670 # 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: End caps # Description and specifications: Central, round end cap with an interpupillary distance scale for the Carl Zeiss Jena wide-field (German: Grossfeld) binocular head. This component is located at the front, in the centre of the binocular head, between the two eyepiece tubes. It is a round cover plate (end cap) carrying a scale from 55 to 75 indicating the interpupillary distance (eyepiece tube spacing). The last photograph in the gallery shows the complete binocular head. An arrow indicates the exact component being offered and its location within the head, allowing it to be identified unambiguously. This is a component of the binocular head rather than a component dedicated to a particular microscope model. This component fits 30 mm eyepiece binocular heads used, among others, on 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. # Examples of use - if this component is missing from your Carl Zeiss Jena binocular head or your Baader Mark V binocular viewer # 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 central cover - Carl Zeiss Jena Jenaval / Jenamed Mikroskop Grossfeld Binokularkopf Endkappe - 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/99670.md - Markdown auf Deutsch: https://www.mikroskopteile.de/part/99670.md - Gallery of all photos of this part: https://www.microscopeparts.eu/gallery/99670-carl-zeiss-jena-jenaval-jenamed-microscope-central-round-end-cap-with-interpillary-distance-scale-for-30-mm-wide-field - Media manifest of this part (photos + videos, for AI/RAG): https://www.microscopeparts.eu/part/99670.media.md - Representative photo: https://www.microscopeparts.eu/photo/carl-zeiss-jena-jenaval-jenamed-microscope-central-round-end-cap-with-interpillary-distance-scale-for-30-mm-wide-field-99670-2 - Other parts from category End caps: https://www.microscopeparts.eu/end-caps - More End caps removed from microscope Carl Zeiss Jena Jenaval: https://www.microscopeparts.eu/end-caps/from/carl-zeiss-jena/jenaval - More End caps compatible with microscope Carl Zeiss Jena Jenaval: https://www.microscopeparts.eu/end-caps/for/carl-zeiss-jena/jenaval - More End caps removed from microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/end-caps/from/carl-zeiss-jena - More End caps compatible with microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/end-caps/for/carl-zeiss-jena # Important information: Database Description: Technical microscope parts database based on years of practical service experience.
