🔬 Olympus BH2-RFCA epi-fluorescence illuminator for BH2 series, BHT, BHTU, and BHS upright microscopes⚡ Epi-fluorescence (reflected light) design — excitation light delivered through the objective for maximum specimen illumination efficiency🎯 Broad BH2 platform compatibility — fits all BH2 series microscopes as well as BHT, BHTU, and BHS platforms🏭 Made in Japan by Olympus — guaranteed OEM fit and optical performance on BH2 series platforms✅ SKU BH2-RFCA / Cat. 5-LB277 — excellent condition, significant savings vs. list price of $1,850 🔧 Product Description The Olympus BH2-RFCA is an epi-fluorescence illuminator for Olympus BH2 series upright microscopes, as well as the BHT, BHTU, and BHS platforms. It adds epi-fluorescence (reflected light fluorescence) capability to these classic Olympus upright microscope platforms, enabling fluorescence observation of specimens using filter cubes installed in the illuminator's filter cube turret. In epi-fluorescence illumination, excitation light from the lamp source is directed down through the objective onto the specimen — the objective acts as both the condenser and the collection lens, maximizing excitation efficiency and minimizing background fluorescence. The BH2-RFCA is the correct OEM fluorescence illuminator for the BH2 series platform — an essential upgrade or replacement component for researchers and institutions maintaining Olympus BH2, BHT, BHTU, or BHS microscopes in active fluorescence service. Built to Olympus factory specifications (catalog number 5-LB277). This unit is in excellent condition at a significant discount from the list price. 🔎 Typical Applications Fluorescence microscopy on BH2 series — adding or restoring epi-fluorescence capability to BH2, BHT, BHTU, or BHS upright microscopes Immunofluorescence — multi-label fluorescence observation of antibody-tagged targets in fixed tissue and cell samples FISH (fluorescence in situ hybridization) — fluorescent probe detection in cytogenetics and pathology on BH2 series platforms Fluorescent stain observation — DAPI, FITC, TRITC, and other standard fluorophore excitation via filter cubes in the BH2-RFCA turret Replacement or upgrade fluorescence illuminator for existing BH2, BHT, BHTU, or BHS microscopes 📊 Key Specifications Specification Details Olympus Part Number BH2-RFCA (5-LB277) Type Epi-Fluorescence Illuminator Illumination Mode Epi-fluorescence (reflected light) Compatible Microscopes Olympus BH2 series, BHT, BHTU, BHS Country of Origin Japan HS Code 901190 Condition Excellent Universities and research institutions are welcome to purchase using an official purchase order.
