# Part name: Carl Zeiss Jena Jenamed microscope condenser iris diaphragm # Original page URL: https://www.microscopeparts.eu/part/carl-zeiss-jena-jenamed-microscope-condenser-iris-diaphragm-99457 # 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: Iris diaphragms # Description and specifications: Iris diaphragm for the microscope condenser of Carl Zeiss Jena Jenamed microscopes. This is an aperture diaphragm. This particular example shown and offered here was removed from a Carl Zeiss Jena Jenamed Cytology microscope. It will most likely also fit other models from the Jenamed series (e.g. Jenamed Variant, Jenamed Fluorescence, Jenamed-2, Jenamed Hematology). It does not fit the Jenamed Histology model because the Carl Zeiss Jena Jenamed Histology microscope features a different type of condenser (a 'flip-out' type) by default. For this reason, the iris diaphragm is located slightly lower than in other models and is different. To make sure whether this iris diaphragm will fit a specific Carl Zeiss Jena microscope from the Jenamed series, it is best to carefully check all dimensions based on the gallery photos or ask a question on a professional forum, e.g. https://www.mikroskopie-forum.de/ Mechanically, this diaphragm is mounted underneath the condenser. The entire diaphragm module is attached to the microscope body with four screws. It is not mechanically connected to the condenser - these are separate elements. The lever pin used to open / close the diaphragm protrudes through a special opening at the front of the microscope, making it possible to adjust the diaphragm opening. This opening is located in the cover of the filter wheel - here one can see further relationships between the individual elements of the light path. Carl Zeiss Jena Jenamed microscopes do not have a field diaphragm. Replacement of the aperture diaphragm module in a Carl Zeiss Jena Jenamed microscope may be necessary: - when some of the iris diaphragm blades become damaged (bent or broken) - when the lever used to open / close the diaphragm breaks off - when the teeth of the gear wheel mounted in this module become damaged Metal cast or injection-moulded microscope parts made by Carl Zeiss Jena have their own numbers. This part carries the number 2713 (full marking: Si10 CZ 2713). # Examples of use - as a repair part in the form of replacing the complete part if it or one of its elements is damaged or of very poor quality - several examples of applications are given in the description - if you want to use such a module with iris diaphragm for your own DIY projects. # Removed from microscope: Carl Zeiss Jena Jenamed # Also compatible with the following microscopes: Carl Zeiss Jena Jenamed # Names, descriptions, terms, and search contexts under which this part is searched. - Carl Zeiss Jena Jenamed microscope repair parts - Carl Zeiss Jena Jenamed microscope condenser iris diaphragm - Jenamed microscope aperture diaphragm - przysłona irysowa do mikroskopu Carl Zeiss Jena Jenamed - Carl Zeiss Jena Jenamed Mikroskop-Kondensor Irisblende - Jenamed Mikroskop Aperturblende - Carl Zeiss Jena buy spare parts # Related URLs: - Markdown po polsku: https://www.serwismikroskopowy.pl/part/99457.md - Markdown auf Deutsch: https://www.mikroskopteile.de/part/99457.md - Gallery of all photos of this part: https://www.microscopeparts.eu/gallery/99457-carl-zeiss-jena-jenamed-microscope-condenser-iris-diaphragm - Media manifest of this part (photos + videos, for AI/RAG): https://www.microscopeparts.eu/part/99457.media.md - Representative photo: https://www.microscopeparts.eu/photo/carl-zeiss-jena-jenamed-microscope-condenser-iris-diaphragm-99457-2 - Representative video: https://www.microscopeparts.eu/play/99457-1 - Other parts from category Iris diaphragms: https://www.microscopeparts.eu/iris-diaphragms - More Iris diaphragms removed from microscope Carl Zeiss Jena Jenamed: https://www.microscopeparts.eu/iris-diaphragms/from/carl-zeiss-jena/jenamed - More Iris diaphragms compatible with microscope Carl Zeiss Jena Jenamed: https://www.microscopeparts.eu/iris-diaphragms/for/carl-zeiss-jena/jenamed - More Iris diaphragms removed from microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/iris-diaphragms/from/carl-zeiss-jena - More Iris diaphragms compatible with microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/iris-diaphragms/for/carl-zeiss-jena # Important information: Database Description: Technical microscope parts database based on years of practical service experience.
