Olympus CX31-P Polarized Light Microscope

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.
