Olympus BH2-RFCA Fluorescence Illuminator

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.
