The Olympus CX31-P Polarized Light Microscope is a fully configured, research-grade polarizing microscope built for birefringence analysis, crystal examination, and materials characterization — complete with a rotating stage, compensator system, and a comprehensive set of strain-free optics. 🔵 360° rotating ball-bearing polarized light stage for precise specimen orientation and extinction angle measurement 🔬 4x, 10x, 20x, and 40x Plan objectives covering the full magnification range for polarized light work 🔮 Strain-free condenser with rotatable polarizer for accurate birefringence and interference color analysis 🧪 U-ANT analyzer, U-KPA intermediate attachment, U-TAD compensator adapter, and U-TP530 first-order red gypsum plate for advanced compensator and retardation measurements 👁️ Binocular head with WHB 10x widefield eyepieces — crosshair reticle installed in right eyepiece for precise alignment ✅ Condition: Refurbished, Excellent — inspected and performance-verified 🔧 Product Description The Olympus CX31-P is a high-quality polarizing microscope combining wide-ranging analytical capability with outstanding optical performance and durability. Its 360° rotating ball-bearing stage enables smooth, precise specimen rotation for extinction angle measurement and crystal orientation analysis. The strain-free condenser with rotatable polarizer ensures accurate polarized light transmission without introducing optical artifacts. Four Plan objectives — 4x, 10x, 20x, and 40x — provide flat, sharp imaging across the full magnification range required for polarized light work. The U-KPA intermediate attachment and U-TAD compensator adapter accept the included U-TP530 first-order red (gypsum) full-wave plate, enabling interference color analysis and retardation measurements essential for mineralogy, petrology, and materials science. The U-ANT analyzer completes the crossed-polarizer optical train. WHB 10x widefield eyepieces provide comfortable, high-contrast observation, with a crosshair reticle installed in the right eyepiece for precise specimen alignment and measurement. This unit has been professionally refurbished to excellent condition and is ready for immediate use. 🔎 Typical Applications Mineralogy and petrology thin section analysis Crystal structure and birefringence examination Interference color and retardation measurement with compensators Pharmaceutical polymorphism and crystal habit analysis Fiber identification and forensic materials analysis Quality control of optically active materials and coatings 📊 Key Specifications Specification Details Frame Olympus CX31-P Head Binocular Eyepieces WHB 10x Widefield (crosshair reticle in right eyepiece) Objectives Plan 4x, Plan 10x, Plan 20x, Plan 40x Stage 360° rotating ball-bearing polarized light stage Condenser Strain-free with rotatable polarizer Analyzer U-ANT Intermediate Attachment U-KPA Compensator Adapter U-TAD Compensator Plate U-TP530 First-Order Red Full-Wave Gypsum Plate Condition Refurbished, Excellent SKU CX31P Country of Origin Japan Weight 35 lbs University and institutional purchase orders are welcome.
