🔬 Olympus BH2-UMA universal reflected light illuminator for BH2 series upright metallograph microscopes⚡ Universal metallograph attachment — supports brightfield, darkfield, and polarized reflected light illumination modes on BH2 series platforms🎯 Multi-mode reflected light — switchable between BF, DF, and POL for comprehensive opaque specimen analysis in a single illuminator🏭 Made in Japan by Olympus — guaranteed OEM fit and optical performance on BH2 series platforms✅ SKU BH2-UMA — excellent condition, significant savings vs. list price of $1,650 🔧 Product Description The Olympus BH2-UMA is a universal reflected light illuminator (metallograph attachment) for Olympus BH2 series upright microscopes, providing brightfield (BF), darkfield (DF), and polarized (POL) reflected light illumination modes for comprehensive opaque specimen analysis. In reflected light microscopy, the illumination is delivered through the objective onto the specimen surface and reflected back up through the same objective to the observer — making it the standard approach for metallography, materials science, and mineralogy where specimens are opaque and cannot be observed in transmitted light. The BH2-UMA’s universal design supports all three primary reflected light contrast modes: brightfield for standard surface observation, darkfield for high-contrast detection of surface defects and grain boundaries, and polarized light for revealing anisotropic features, grain orientation, and birefringent phases in metals, alloys, and ore minerals. The BH2-UMA accepts polarizing accessories including the UPO-NIC rotatable polarizer for full reflected light POL capability. It is the correct OEM reflected light illuminator for the BH2 series metallograph platform — an essential replacement or upgrade component for researchers and institutions maintaining BH2 series microscopes in active metallographic service. This unit is in excellent condition at a significant discount from the list price. 🔎 Typical Applications Metallography — brightfield, darkfield, and polarized reflected light analysis of polished metal sections, grain structure, and phase identification Materials science — reflected light inspection of polished alloys, ceramics, composites, and coatings on BH2 series platforms Ore mineralogy — reflected light POL identification of ore minerals by optical properties (reflectance, anisotropy, bireflectance) Electronics and semiconductor inspection — reflected light surface analysis of polished wafers, PCBs, and electronic components Replacement or upgrade reflected light illuminator for existing BH2 series metallograph microscopes 📊 Key Specifications Specification Details Olympus Part Number BH2-UMA Type Universal Reflected Light Illuminator (Metallograph Attachment) Illumination Modes Brightfield (BF), Darkfield (DF), Polarized (POL) Compatible Microscopes Olympus BH2 series HS Code 901190 Condition Excellent Universities and research institutions are welcome to purchase using an official purchase order.
