The Olympus BHT Reflected & Transmitted Light Brightfield, Darkfield & DIC Microscope is a fully configured, research-grade dual-mode system combining reflected light brightfield, darkfield, and DIC/Nomarski with transmitted light — featuring four Neo SPlan objectives with integrated DIC prisms, a large 4” × 4” XY travel stage, and a trinocular head for versatile materials science and industrial inspection applications. 🔬 Four Neo SPlan objectives with integrated DIC prisms: 10x, 20x, 50x, and 100x — each with a matched Nomarski prism for immediate DIC imaging at any magnification 🌀 BD vertical illuminator with 12V 100W quartz halogen for brightfield and darkfield reflected light 🔵 DIC/Nomarski system: integrated objective prisms, 360° rotatable polarizer, and analyzer for high-contrast surface topography imaging 📍 Large 4” × 4” XY travel stage for accommodating large specimens, wafers, and substrates 📷 3-position trinocular head for simultaneous observation and camera documentation ✅ Condition: Refurbished, Excellent — inspected and performance-verified 🔧 Product Description The Olympus BHT is a proven, research-grade reflected and transmitted light microscope with a long track record in materials science, metallurgy, and industrial inspection laboratories. This configuration is particularly notable for its four Neo SPlan objectives — 10x, 20x, 50x, and 100x — each with an integrated DIC prism, enabling immediate Nomarski DIC imaging at any magnification without manual prism insertion or alignment. The BD vertical illuminator with 12V 100W quartz halogen lamphouse delivers bright, stable reflected light illumination for both brightfield and darkfield modes. The 360° rotatable polarizer and analyzer complete the DIC optical train, enabling high-contrast three-dimensional surface topography imaging that reveals grain boundaries, thin film structures, surface relief, and microelectronic features. Darkfield mode highlights surface defects, scratches, and particles invisible in brightfield. The quartz halogen transmitted light path adds brightfield transmitted light capability for thin sections and transparent specimens. The large 4” × 4” XY travel stage accommodates large specimens, semiconductor wafers, and substrates that smaller stages cannot handle. The 3-position trinocular head supports simultaneous observation and digital documentation. Professionally refurbished to excellent condition. 🔎 Typical Applications Metallurgical analysis and grain structure examination Semiconductor wafer and large substrate inspection Reflected light DIC for surface topography and relief imaging Darkfield inspection of surface defects, scratches, and particles Thin film and coating surface characterization Quality control and failure analysis in industrial settings 📊 Key Specifications Specification Details Frame Olympus BHT (reflected & transmitted light) Head 3-position trinocular Objectives Neo SPlan 10x (DIC), Neo SPlan 20x (DIC), Neo SPlan 50x (DIC), Neo SPlan 100x (DIC) Reflected Illuminator BD vertical illuminator, 12V 100W quartz halogen (brightfield/darkfield) DIC System Integrated objective prisms, 360° rotatable polarizer, analyzer Transmitted Illumination Quartz halogen transmitted light Stage 4” × 4” XY travel stage Condition Refurbished, Excellent SKU BHT-DIC Country of Origin Japan Weight 50 lbs University and institutional purchase orders are welcome.
