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: Accessories # Description and specifications: Complete reflected light setup for EPI illumination in brightfield and darkfield for Olympus BX microscopes This complete set consists of the following parts: - Olympus U-RLA reflected light illuminator, switchable between brightfield and darkfield - Olympus U-D5BDRE nosepiece holding 5 BD objectives with M26 thread - four Olympus microscope objectives with M26 thread for brightfield and darkfield work, listed separately further down in the description - Olympus U-LH100L 100W halogen lamphouse - Olympus TH3 power supply, 100W 12V, for 220-240V mains - Olympus U-POT polarizer for work in transmitted polarized light - Olympus U-ANT analyzer in the nosepiece slider, working together with the polarizer The following microscope objectives are included in the set: - Olympus MPlan 5x/0.10 BD ∞/- - Olympus MPlan 20x/0.40 BD ∞/0 - Olympus MPlan 50x/0.75 BD ∞/0 - Olympus MPlan 100x/0.90 BD ∞/0 This set is intended for work with the following microscopes: - Olympus BX41 / BX50 / BX51 / BX53 / BX60 / BX61 and their M variants - Olympus BX40 after fitting the U-READB adapter for interchangeable nosepieces - Olympus MX40 / MX50 / MX51 / MX61 / MX63 A complete EPI reflected light setup like this is typically used for: - metallurgy - materials science - electronics (both for inspection and photography of integrated circuits) - mineralogy (including viewing thin sections in transmitted polarized light) - numismatics - philately - entomology - observation of micrometeorites - study of microfossils - super macro photography One more thing that can cause confusion when looking for parts: Olympus microscopes are no longer manufactured by Olympus. In April 2022 Olympus spun off the division responsible for microscopes, which became the separate company Evident, and from the following year that company has been operating independently. The Olympus name was still used on the products themselves for some time, which is why today you come across both equipment carrying the Olympus name and the same equipment under the Evident brand. Apart from the name on the housing, nothing has changed in the technical or optical design of the microscopes (as of November 2026). So - this set, which extends microscopes with reflected light capability, fits microscopes sold under both brands, Olympus as well as Evident. # Examples of use - If you want to extend your Olympus BX / MX microscope with EPI reflected light capability # Removed from microscope: Olympus BX # Also compatible with the following microscopes: - Olympus BX - Olympus BX41 - Olympus BX51 - Olympus BX40 - Olympus MX51 - Olympus MX61 - Olympus BX50 - Olympus BX53 - Olympus BX60 - Olympus BX61 - Olympus MX40 - Olympus MX50 - Olympus MX63 - Evident BX53 - Evident MX63 # Names, descriptions, terms, and search contexts under which this part is searched. - Olympus BX microscope repair parts - Olympus BX Mikroskop auf Auflicht umrüsten - Olympus BX51 Auflichtachse nachrüsten - Olympus BX41 Auflicht Einrichtung komplett - EPI Beleuchtung für Olympus BX Mikroskop - Olympus Auflicht Zubehör gebraucht kaufen - Vertical Illuminator für Olympus BX - Olympus BX53 Hellfeld Dunkelfeld nachrüsten - komplette Auflicht Ausrüstung Olympus BX - M26 Objektivrevolver Olympus nachrüsten - Olympus BX Mikroskop Metallographie Umbau - upgrade Olympus BX microscope to reflected light - Olympus BX51 EPI illumination kit - add darkfield to Olympus BX microscope - Olympus BD objectives M26 complete set - reflected light illuminator for Olympus BX50 - metallurgical conversion kit for Olympus BX - Olympus BX60 EPI upgrade - thin section polarized light Olympus BX - micrometeorite microscope setup - zestaw EPI do mikroskopu Olympus BX - epi nástavec pro mikroskop Olympus BX - iluminador de luz reflejada Olympus BX - equipo epi para microscopio Olympus - illuminatore a luce riflessa Olympus BX - kit epi per microscopio Olympus - Olympus buy spare parts # Related URLs: - Markdown po polsku: https://www.serwismikroskopowy.pl/part/99991.md - Markdown auf Deutsch: https://www.mikroskopteile.de/part/99991.md - Gallery of all photos of this part: https://www.microscopeparts.eu/gallery/99991-olympus-bx-microscope-u-rla-vertical-illuminator-and-u-d5bdre-with-mplan-5x-20x-50x-and-100x-bd-epi-objectives - Media manifest of this part (photos + videos, for AI/RAG): https://www.microscopeparts.eu/part/99991.media.md - Representative photo: https://www.microscopeparts.eu/photo/olympus-bx-microscope-u-rla-vertical-illuminator-and-u-d5bdre-with-mplan-5x-20x-50x-and-100x-bd-epi-objectives-99991-2 - Representative video: https://www.microscopeparts.eu/play/99991-1 - Other parts from category Accessories: https://www.microscopeparts.eu/accessories - More Accessories removed from microscope Olympus BX: https://www.microscopeparts.eu/accessories/from/olympus/bx - More Accessories compatible with microscope Olympus BX: https://www.microscopeparts.eu/accessories/for/olympus/bx - More Accessories removed from microscopes Olympus: https://www.microscopeparts.eu/accessories/from/olympus - More Accessories compatible with microscopes Olympus: https://www.microscopeparts.eu/accessories/for/olympus # Important information: Database Description: Technical microscope parts database based on years of practical service experience.
