Precision in Polarizing Microscopy

Engineered for professional material analysis, the PQR-500S blends a sophisticated polarizing optical system with a rotatable 360 polarizer and analyzer, plus a centerable Bertrand lens. The mechanical stage features click-stops and a vernier scale for meticulous sample orientation. With graduated rotation and fine focus adjustments, users can achieve pinpoint accuracy in imaging, making it ideal for geological and industrial applications demanding high-detail observations.

Superior Imaging and Ergonomics

Equipped with a high-resolution CMOS sensor and USB 3.0 connectivity, the microscope simplifies capturing and sharing images or videos at 5 MP still and Full HD 1080p respectively. Its trinocular head provides comfortable viewing, further enhanced by diopter-adjustable widefield eyepieces and ergonomic arm rest. The adjustable LED illumination ensures optimal sample visualization under varying contrast and lighting conditions.

FAQs of Upright Polarizing Microscope PQR-500S:

Q: How do I rotate and lock the polarizer and analyzer on the PQR-500S?

A: The polarizer on the PQR-500S features a full 360 rotation, allowing precise control over polarization axes. The analyzer is rotatable as well and can be locked into position for consistent results, enhancing the reliability of birefringence analysis and interference pattern observation.

Q: What steps should I follow to capture high-resolution images and videos with this microscope?

A: To capture still images (5 MP) or Full HD 1080p videos, connect the microscope to your computer via the USB 3.0 interface. Use supported imaging software to access the CMOS sensor, then adjust focus and illumination as needed. Images can be saved in JPEG, BMP, or TIFF formats.

Q: When should I utilize the swing-out Bertrand lens during observation?

A: The swing-out, centerable Bertrand lens is used when you need to observe interference figures or conoscopic images, typically during the identification of mineral optical properties. Swing it into the light path when such observations are required, and retract it for standard viewing.

Q: Where are the stage movement controls located and how do they enhance analysis?

A: The graduated rotatable stage, with a 160 mm diameter, includes click-stops and is operated via side-mounted controls. This design helps maintain specimen orientation and enables accurate angular measurements, essential for precise mineral analysis and orientation studies.

Q: What is the benefit of the anti-fungal optics coating and hard anodized surfaces?

A: Anti-fungal coatings on the optical components prevent mold growth in humid environments, ensuring consistent optical clarity. Hard anodized, scratch-resistant stage surfaces extend the microscopes life and maintain its smooth operation even after extensive use.

Q: How should I maintain and store the microscope for long-term performance?

A: After each use, cover the microscope with the included dust cover and store it in a dry area within the operational temperature and humidity specs (540C, max 80% RH non-condensing). Regularly clean the optics with appropriate materials and use the included user manual for guidance on maintenance routines.
