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: 450 nm fluorescence filter cube for Carl Zeiss Jena Fluoval-2 and Laboval Fluoreszenz fluorescence microscopes. This filter cube, sometimes also called a reflector, performs two functions: - it contains a barrier filter (emission filter) for the 450 nm wavelength - it acts as an angular mirror, reflecting the light beam from the EPI fluorescence illuminator vertically downward through the objective toward the specimen. This fluorescence filter cube fits the following EPI fluorescence microscopes: - Carl Zeiss Jena Fluoval Fluoreszenz - Carl Zeiss Jena Fluoval-2 (built on the Carl Zeiss Jena Amplival microscope platform) Important – this microscope component does not fit the first version of the Carl Zeiss Jena Fluoval microscope. The Fluoval microscope (without "2") does not use a filter cube. Instead, it has a simple permanently mounted swing-out barrier filter. The filter cube has two positions: - empty, for normal transmitted-light operation - 450 nm for reflected-light fluorescence (EPI) operation Mechanically, this filter cube is installed between the objective nosepiece and the microscope head. It slides into a dedicated slot and moves along a dovetail guide. On the Carl Zeiss Jena Laboval Fluoreszenz microscope, this slot is located in the additional upper horizontal arm of the EPI fluorescence illuminator. On the Carl Zeiss Jena Fluoval-2 microscope, the slot is located in the EPI fluorescence arm, which is an integral part of the microscope. The Fluoval-2 is based on the Carl Zeiss Jena Amplival microscope, which has a modular design. Mechanically, the Fluoval-2 is essentially an Amplival equipped with an upper EPI fluorescence arm. Sliding the cube along this dovetail guide switches between the empty position (transmitted light) and EPI fluorescence with the 450 nm filter. # Examples of use - if you own a Carl Zeiss Jena Fluoval-2 or Laboval Fluoreszenz microscope with this filter cube missing # Removed from microscope: Carl Zeiss Jena Fluoval-2 # Also compatible with the following microscopes: - Carl Zeiss Jena Fluoval-2 - Carl Zeiss Jena Laboval Fluorescence # Names, descriptions, terms, and search contexts under which this part is searched. - Carl Zeiss Jena Fluoval-2 microscope repair parts - Carl Zeiss Jena Fluoval-2 Mikroskop Fluoreszenz-Filterwürfel / Filterschieber 450nm - Carl Zeiss Jena Laboval Fluoreszenz Mikroskop Filterwürfel 450nm - Carl Zeiss Jena Fluoval-2 microscope fluorescence filter cube 450nm - Carl Zeiss Jena Laboval Fluorescence microscope filter cube 450nm - Carl Zeiss Jena buy spare parts # Related URLs: - Markdown po polsku: https://www.serwismikroskopowy.pl/part/99697.md - Markdown auf Deutsch: https://www.mikroskopteile.de/part/99697.md - Gallery of all photos of this part: https://www.microscopeparts.eu/gallery/99697-carl-zeiss-jena-fluoval-2-laboval-fl-microscope-fluorescence-filter-cube-450nm - Media manifest of this part (photos + videos, for AI/RAG): https://www.microscopeparts.eu/part/99697.media.md - Representative photo: https://www.microscopeparts.eu/photo/carl-zeiss-jena-fluoval-2-laboval-fl-microscope-fluorescence-filter-cube-450nm-99697-2 - Representative video: https://www.microscopeparts.eu/play/99697-1 - Other parts from category Filters: https://www.microscopeparts.eu/filters - More Filters removed from microscope Carl Zeiss Jena Fluoval-2: https://www.microscopeparts.eu/filters/from/carl-zeiss-jena/fluoval-2 - More Filters compatible with microscope Carl Zeiss Jena Fluoval-2: https://www.microscopeparts.eu/filters/for/carl-zeiss-jena/fluoval-2 - 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.
