Nikon Optiphot-POL Reflected & Transmitted Light Polarized Light Microscope — Complete System (OPTIPHOT-POL) 🔬 Dual reflected & transmitted polarized light — full POL capability for both opaque and transparent specimens 🔄 360° rotating circular stage — precise specimen rotation for extinction angle measurement and birefringence analysis 🔭 360° polarizer + analyzer — full crossed-polar configuration with swing-out condenser 🎯 4-objective M Plan set — 5X, 10X (x2), and 40X M Plan objectives included 📷 3-position trinocular head — flexible light path switching for eyepiece, camera, or split viewing ✅ Condition: Excellent 🔧 Product Description The Nikon Optiphot-POL is a dedicated research-grade polarized light microscope engineered for both reflected and transmitted polarization work. Unlike general-purpose microscopes adapted for POL use, the Optiphot-POL is purpose-built with a strain-free optical train, a precision 360° rotating circular stage, and a full polarizer/analyzer system — delivering the optical performance required for quantitative birefringence analysis, extinction angle measurement, and crystal characterization. The dual illumination capability is a key strength: reflected light mode is used for opaque specimens such as polished metals, ores, ceramics, and semiconductor materials, while transmitted light mode handles transparent and semi-transparent specimens including minerals, crystals, fibers, bone, and polymers. The swing-out condenser allows rapid switching between the two modes without disturbing the specimen. This complete system includes four M Plan objectives (5X, 10X, 10X, 40X), a 3-position trinocular head with 10X eyepieces, a reflected light illuminator, and the full polarizer/analyzer assembly. The 3-position trinocular head provides flexible light path distribution for simultaneous or switched eyepiece and camera use. This unit is in excellent condition. 🔎 Typical Applications Mineralogy and petrology — crystal identification and thin section analysis Metallurgy — grain structure and phase identification in polished metal sections Materials science — polymer, fiber, and composite birefringence analysis Semiconductor and electronics inspection under reflected polarized light Forensic science — fiber, paint chip, and mineral particle identification 📊 Key Specifications & Included Components Component / Specification Details Model Nikon Optiphot-POL SKU OPTIPHOT-POL Manufacturer Nikon Microscope Type Polarized light — reflected & transmitted Head Type 3-position trinocular Eyepieces 10X Objectives Included M Plan 5X, M Plan 10X (x2), M Plan 40X Stage 360° rotating circular stage Polarizer 360° rotating polarizer Analyzer Included Condenser Swing-out Reflected Light Illuminator Included Country of Origin Japan Condition Excellent 📋 University and institutional purchase orders accepted.
