🔧 Product Description

The Olympus BX51-P Polarized Light Microscope is a professional research instrument designed for advanced polarization microscopy applications in geology, materials science, and crystallography. This complete system combines Olympus's proven BX series platform with specialized polarization optics and accessories, delivering exceptional performance for petrographic analysis, mineral identification, birefringence measurements, and interference figure observation.

At the core of the system is the U-SRP circular rotating stage, featuring precision ball-bearing construction for smooth, accurate 360° rotation with degree markings for extinction angle measurements. The stage accepts the U-FMP attachable mechanical stage, which provides knurled X-Y controls for precise specimen positioning while maintaining full rotational capability — essential for systematic petrographic examination and crystal orientation studies.

The optical train is optimized for polarization work, featuring a U-POC strain-free condenser with a 360° rotatable polarizer, swing-out top lens, and adjustable click-stop at the zero position. This condenser design ensures accurate crossed-polarizer alignment and facilitates both low- and high-magnification observation. The U-AN360P analyzer provides 360° rotation with a locking function, enabling precise control over polarization orientation for extinction measurements and optical property determination.

Four strain-free polarization objectives (4×, 10×, 20×, and 40×) are mounted on the U-P4RE centerable quadruple nosepiece. Each objective position features individual centering adjustments, allowing precise alignment of the optical axis with the stage rotation center — critical for accurate conoscopic observation and interference figure analysis. The strain-free optical design eliminates internal stress birefringence that could interfere with specimen analysis.

The system includes the U-CPA conoscopic observation attachment with Bertrand field stop, enabling the transition from orthoscopic (standard) to conoscopic (interference figure) observation modes. This capability is essential for determining optical character, optic sign, and other diagnostic optical properties of minerals and crystals. The U-TAD compensator adapter accepts the included U-TP530 first-order red (full-wave) gypsum plate, facilitating retardation measurements and birefringence characterization.

The U-TR30-2 trinocular head offers three light distribution positions (100:0, 80:20, 0:100), allowing simultaneous visual observation and photography or digital imaging. The system includes WHN 10× widefield eyepieces with a crosshair reticle and scale installed in the right eyepiece for measurement and alignment reference.

This microscope is in excellent, as-new working condition, ready for immediate deployment in research, academic, or industrial laboratory settings.
