I. Product Overview
The CX-P adopts an infinity color-corrected optical system, equipped with plan achromatic infinity stress-free objectives (5X/10X/20X/50X) and high-eye-point wide-field plan eyepieces (PL10X/22mm), with a magnification range of 50–500X. It has a built-in Bertrand lens and compensator slot (λ plate / λ/4 plate / quartz wedge) to support conoscopic interference observation. The plug-in polarizer can rotate 360° (scale value: 2°, accuracy: 6′), and the 160 mm large-diameter graphite-coated stage enables 360° rotation and locking. Featuring a Y-shaped roof high-rigidity body and modular assembly structure, it is compatible with transmitted and reflected illumination. A digital imaging module is optional. It is widely applied in geological mineral identification, material crystal analysis, textile fiber inspection, glass and ceramic quality testing, biomedical crystal observation and other fields. Continuous technological innovation is dedicated to delivering a more vivid visual experience. By improving the stress-free imaging system and optimizing the reflected illuminator, the CX-P series achieves higher polarization in the lamp house and more vivid image quality. It complies with the company’s HSF environmental policy and innovatively implements eco-friendly manufacturing processes. Various ergonomic and thoughtful designs deliver easier and more comfortable operation.
