Olympus BHT Brightfield Darkfield Reflected Light DIC microscope

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.
