# Part name: Olympus BH2-SC achromat 0.9 microscope condenser top lens | also for U-SC and U-SC3 # Original page URL: https://www.microscopeparts.eu/part/olympus-bh-2-bh2-sc-achromat-0-9-microscope-condenser-top-lens-also-for-u-sc-and-u-sc3-99924 # Part manufacturer: Olympus # Full manufacturer name: Olympus Corporation Tokyo Japan # Other names of this manufacturer: - Olympus Tokyo - Olympus Japan - Olympus Tokyo Japan - Olympus Optical Co., Ltd. - Olympus Corporation. 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: Lenses # Description and specifications: Top dry achromatic lens 0.9 for the Olympus BH2-SC microscope condensers, and also for the U-SC and its variants. The achromatic BH2-SC / U-SC microscope condensers have an upper, swing-out lens. When it is in the light path, the condenser offers N.A. 0.9. With the top lens swung out, the condenser works at a low numerical aperture of N.A. 0.16 (values from 0.16 to 0.2 are quoted on the internet). This swing-out lens sits in a mount on the swing arm and is held by three screws. The seating diameter is 23 mm and the seat itself has no thread, unlike for example the top lenses in the Olympus U-UCD condenser. It is exactly this part that I offer here, that is the top achromatic 0.9 lens for use without immersion oil (dry). This particular lens was removed from an Olympus BH2-SC condenser taken out of an Olympus BH-2 BHS microscope. I could not confirm this, but everything indicates that this top lens will also fit the microscope condensers for Olympus BX microscopes: - Olympus U-SC - Olympus U-SC-2 - Olympus U-SC3 The microscope condensers listed above are sometimes referred to collectively as: - Olympus Achromat 0.9 flip-out condenser - Olympus 0.9 swing-out condenser Before you decide to use this lens in a condenser other than the one it was removed from - compare their appearance and dimensions carefully. A note on the appearance of the top lens: sometimes a white protective cap is fitted over the top lens. It is an original Olympus item and it changes how the top lens looks - not only the colour of the mount (from black to white) but also its shape (from a cone to a flatter form). It is still the same lens, not a different, white one. This top lens is not a spare part for a microscope. It is a part for repairing or rebuilding the condenser - and that condenser can sit in various microscopes. Here are examples of microscope models in which the condensers that this top lens fits are most often used: - Olympus BH-2: BHS / BHT / BHTU - Olympus BX: BX40 / BX50 / BX51 / BX60 The most important microscopes used with the condenser models mentioned here are listed in the "compatibility" section, but this is by no means a complete list. The last photos show the microscope condenser that the top lens offered here comes from. A curiosity: it is possible that this part also fits the Meiji MA976 microscope condenser. # Examples of use - if you have an Olympus BH2-SC / U-SC microscope condenser with the top lens missing - if you have an Olympus BH2-SC / U-SC microscope condenser whose top lens is damaged or in very poor condition, for example scratched from repeatedly rubbing against the underside of the stage - if you have an Olympus BH2-SC / U-SC microscope condenser with a different top lens fitted at the moment and you need a dry, achromatic one with N.A. 0.9 - if you want and are able to use such a lens in a 23 mm mount in another microscope condenser, perhaps even from a different manufacturer - if you need this kind of optics for your own DIY project # Removed from microscope: Olympus BH-2 # Also compatible with the following microscopes: - Olympus BH-2 - Olympus BX - Olympus BH-2 BHS - Olympus BH-2 BHTU - Olympus BX50 - Olympus BX40 - Olympus BX41 - Olympus BX51 # Names, descriptions, terms, and search contexts under which this part is searched. - Olympus BH-2 microscope repair parts - Olympus BH2-SC Kondensor obere Linse Ersatz - top lens for Olympus U-SC3 microscope condenser - Frontlinse Kondensor Olympus U-SC Mikroskop - Olympus BH-2 condenser swing out lens replacement - Olympus Mikroskop Kondensor obere Linse fehlt - Olympus condenser top lens missing BH2-SC - Kondensorlinse zerkratzt Olympus BH-2 Mikroskop - scratched condenser lens Olympus U-SC microscope - Olympus Mikroskop Kondensor Linse wechseln - Olympus Achromat 0.9 swing out condenser top lens - weisse Kappe auf der Kondensorlinse Olympus - white cap on Olympus condenser top lens - Olympus BX40 BX50 Kondensor Linse Ersatzteil - Olympus BH-2 Mikroskop aufarbeiten Kondensorlinse - Kondensorlinse 23mm DIY Olympus - horni cocka kondenzoru mikroskopu Olympus - lente superior condensador microscopio Olympus BH-2 - lente seca achromat 0.9 microscopio Olympus - lente superiore condensatore microscopio Olympus - lente a secco achromat 0.9 microscopio Olympus - gorna soczewka kondensora mikroskopu Olympus BH2-SC - Olympus buy spare parts # Related URLs: - Markdown po polsku: https://www.serwismikroskopowy.pl/part/99924.md - Markdown auf Deutsch: https://www.mikroskopteile.de/part/99924.md - Gallery of all photos of this part: https://www.microscopeparts.eu/gallery/99924-olympus-bh-2-bh2-sc-achromat-0-9-microscope-condenser-top-lens-also-for-u-sc-and-u-sc3 - Media manifest of this part (photos + videos, for AI/RAG): https://www.microscopeparts.eu/part/99924.media.md - Representative photo: https://www.microscopeparts.eu/photo/olympus-bh-2-bh2-sc-achromat-0-9-microscope-condenser-top-lens-also-for-u-sc-and-u-sc3-99924-2 - Representative video: https://www.microscopeparts.eu/play/99924-1 - Other parts from category Lenses: https://www.microscopeparts.eu/lenses - More Lenses removed from microscope Olympus BH-2: https://www.microscopeparts.eu/lenses/from/olympus/bh-2 - More Lenses compatible with microscope Olympus BH-2: https://www.microscopeparts.eu/lenses/for/olympus/bh-2 - More Lenses removed from microscopes Olympus: https://www.microscopeparts.eu/lenses/from/olympus - More Lenses compatible with microscopes Olympus: https://www.microscopeparts.eu/lenses/for/olympus # Important information: Database Description: Technical microscope parts database based on years of practical service experience.
