• 🔵 10x, 20x, and 40x POL objectives for standard polarized light observation across the full magnification range
• 🔮 Rotatable analyzer with Bertrand lens for conoscopic interference figure observation and optical axis determination
• 🧪 530nm full wave plate compensator for interference color and retardation analysis
• 🌀 Large rotating ball-bearing stage for precise extinction angle measurement and crystal orientation analysis
• 📷 3-position trinocular head with 10x eyepieces (one adjustable with crosshair reticle) for observation and documentation
• ✅ Completely refurbished to perform same as new — includes power cord, dust cover, and instruction manual

🔧 Product Description

The Olympus BHSP is widely regarded as one of the finest polarizing microscopes ever produced, and this configuration is specifically equipped for the most demanding analytical polarized light applications — including dispersion staining for asbestos identification and refractive index determination. The McCrone dispersion staining 10x objective is a specialized tool that enables identification of asbestos fibers and other particles by their characteristic dispersion colors in liquids of known refractive index — a technique critical for environmental, occupational health, and forensic analysis. Three standard POL objectives — 10x, 20x, and 40x — cover the full magnification range for routine polarized light observation. The rotatable analyzer unit with Bertrand lens enables conoscopic observation of interference figures for optical axis determination and crystal system identification. The 530nm full wave plate compensator enables interference color and retardation measurement. The flip-top condenser with built-in rotatable polarizer and click stops provides convenient, repeatable polarizer positioning. The large rotating ball-bearing stage enables precise extinction angle measurement. The 4-position centerable POL nosepiece ensures accurate objective centration. The 12V 100W quartz halogen lamphouse provides bright, stable illumination. The 3-position trinocular head with crosshair reticle eyepiece supports simultaneous observation, measurement, and camera documentation. Completely refurbished to perform same as new, this system ships with power cord, dust cover, and instruction manual.
