# Part name: Zeiss Photomicroscope / Universal microscope objective nosepiece male dovetail mount # Original page URL: https://www.microscopeparts.eu/part/zeiss-photomicroscope-universal-microscope-objective-nosepiece-male-dovetail-mount-91041 # Part manufacturer: Zeiss # Full manufacturer name: Carl Zeiss West Germany # Other names of this manufacturer: - Carl Zeiss West - Carl Zeiss West Germany - Opton 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: Service and spare parts # Description and specifications: Objective nosepiece mounting holder (with male dovetail) - a component of the intermediate tube of Carl Zeiss Universal and Photomicroscope microscopes. In Zeiss Universal / Zeiss Photomicroscope class microscopes, the intermediate tube (https://www.microscopeparts.eu/part/99571) contains a mounting part onto which the nosepiece is slid. This nosepiece holder is identical in intermediate tubes without a magnification changer and in those with an Optovar. This is exactly the part offered here - the holder used to attach the nosepiece to the intermediate tube. This nosepiece holder includes: - a male dovetail for mounting the nosepiece - a clamping screw that locks the nosepiece in place once fitted - an empty slot for an optional narrow slider - two blanking covers for this slot - an empty slot for a wide filter slider This holder fits the intermediate tubes used in the following microscopes: - Zeiss Universal - Zeiss Photomicroscope I - Zeiss Photomicroscope II - Zeiss Photomicroscope III / III RS - Zeiss Ultraphot This is a service part for those who need to replace this component in their microscope. It is neither a complete nosepiece nor a complete intermediate tube. Replacing this nosepiece holder can remedy, among others, the following problems: - if the nosepiece wobbles after being mounted in the tube, slides on too easily and does not sit firmly - if the nosepiece clamping screw is bent, broken off or lost - if the slider slot is damaged Over the years, the Carl Zeiss Photomicroscope series microscopes have acquired various names that users commonly call them by. These include, among others: - Zeiss Photomikroskop - PM, e.g. Zeiss PM II or Zeiss PM III - Zeiss Phomi, e.g. Zeiss Phomi II It is also worth mentioning that Zeiss Photomicroscope microscopes were also sold under the Opton brand. See the last photos in the gallery: one shows a complete intermediate tube, with an arrow indicating which part this is and exactly where it is located. The other shows two intermediate tubes side by side - one with the Zeiss logo and an integrated magnification changer, and one with the Opton brand logo, without a magnification changer. The comparison shows that both tubes have the same nosepiece mounting holder. In addition, the video gallery contains a film showing how to remove and insert the blanking covers of the narrow slider slot and how to turn the clamping screw. # Examples of use - as a service part if this component in your microscope is damaged, incomplete, or even missing altogether - if you need a nosepiece holder for your own DIY project # Removed from microscope: Zeiss Photomicroscope # Also compatible with the following microscopes: - Zeiss Universal - Zeiss Photomicroscope - Zeiss Ultraphot - Zeiss Photomicroscope II - Zeiss Photomicroscope III RS # Names, descriptions, terms, and search contexts under which this part is searched. - Zeiss Photomicroscope microscope repair parts - Zeiss Photomicroscope nosepiece dovetail replacement - Zeiss Phomi Objektivrevolver-Halterung reparieren - Zeiss Universal Mikroskop Revolver Schwalbenschwanz - Zeiss Ultraphot microscope loose nosepiece mount - Zeiss PM II Objektivrevolver wackelt - Klemmschraube defekt - Zeiss Photomicroscope III RS nosepiece holder with slider slot - Opton Zwischentubus Revolveraufnahme - Zeiss nosepiece dovetail for DIY microscope build - uchwyt rewolweru obiektywowego mikroskopu Zeiss Photomicroscope na jaskółczy ogon - Zeiss buy spare parts # Related URLs: - Markdown po polsku: https://www.serwismikroskopowy.pl/part/91041.md - Markdown auf Deutsch: https://www.mikroskopteile.de/part/91041.md - Gallery of all photos of this part: https://www.microscopeparts.eu/gallery/91041-zeiss-photomicroscope-universal-microscope-objective-nosepiece-male-dovetail-mount - Media manifest of this part (photos + videos, for AI/RAG): https://www.microscopeparts.eu/part/91041.media.md - Representative photo: https://www.microscopeparts.eu/photo/zeiss-photomicroscope-universal-microscope-objective-nosepiece-male-dovetail-mount-91041-2 - Representative video: https://www.microscopeparts.eu/play/91041-1 - Other parts from category Service and spare parts: https://www.microscopeparts.eu/service-and-spare-parts - More Service and spare parts removed from microscope Zeiss Photomicroscope: https://www.microscopeparts.eu/service-and-spare-parts/from/zeiss/photomicroscope - More Service and spare parts compatible with microscope Zeiss Photomicroscope: https://www.microscopeparts.eu/service-and-spare-parts/for/zeiss/photomicroscope - More Service and spare parts removed from microscopes Zeiss: https://www.microscopeparts.eu/service-and-spare-parts/from/zeiss - More Service and spare parts compatible with microscopes Zeiss: https://www.microscopeparts.eu/service-and-spare-parts/for/zeiss # Important information: Database Description: Technical microscope parts database based on years of practical service experience.
