Product Description
The Polarizing Microscopes models YG1287 and YG1288 are sophisticated instruments designed for advanced optical analysis. Built with an Infinity Optical System, these microscopes offer high-quality imaging capabilities essential for detailed examinations in scientific research and laboratory work. The Seidentopf Trinocular Head inclined at 30 degrees supports a wide interpupillary range of 48~75mm, providing comfort and adaptability to various users.
Both models come equipped with Plan Eyepieces of different capabilities, including crosshair, cross, and gridding, ensuring that users can select the optimal setup for their tasks. Furthermore, they include a Backward Quintuple Nosepiece, which simplifies switching between lenses, and Strainfree LWD Infinity Plan Achromatic Objectives for a range of magnifications — from 5x to 100x. Moreover, the YG1288 is enhanced with additional objectives and features for more diverse functionality.
Key functionalities include a 360° Dial Rotation Analyzer, supporting orthoscopic and conoscopic observations, and a Polarizing Rotatable Stage, crucial for precise sample positioning. The illuminations system is versatile, with adjustable brightness for both reflective and transmitted light, and the working stage is both rotatable and center adjustable. Additionally, the condenser and focusing systems are optimized for precision and ease, with fine adjustments down to 0.001mm.
