Advanced Polarizing Functionality

Designed specifically for mineral and material research, the PQR-500S offers advanced polarizing capabilities with a swing-out Bertrand lens, adjustable polarizer and analyzer, and strain-free objectives, allowing precise conoscopic and orthoscopic observation. These features make it ideal for geology labs and research institutions requiring high precision.

High-Precision Mechanical Stage and Optics

The PQR-500S is equipped with a 360 graduated stage (vernier reading 0.1) and a ball-bearing mounted, centerable quadruple nosepiece. The wide field eyepieces, high eye-point, and coaxial coarse/fine focus provide clear, crisp images, while the durable, powder-coated die-cast metal body resists vibrations and maintains alignment.

Versatile Imaging and Illumination Options

The trinocular head supports direct viewing and simultaneous imaging via a USB-enabled camera (optional). The Kohler illumination, adjustable intensity, and supplied color filters (blue, green, neutral density) ensure optimal lighting for detailed specimen analysis. The removable lamp house and spare parts simplify maintenance and prolong instrument lifespan.

FAQs of ConXport Upright Polarizing Microscope PQR-500S:

Q: How do I utilize the polarizing features for mineral analysis with the PQR-500S microscope?

A: The microscope is designed for polarizing observation with a swing-in/out Bertrand lens, rotatable polarizer, and analyzer. To analyze minerals, position your sample on the rotating stage, adjust polarizer and analyzer angles for contrast, and use the Bertrand lens for conoscopic or orthoscopic methods, which highlight optical properties critical to mineral identification.

Q: What is the process for installing or replacing the illumination bulb?

A: The removable lamp house allows for quick and easy replacement. Simply switch off and unplug the microscope, slide out the lamp house from the base, replace the 6V/20W halogen bulb, and insert the lamp house back securely. Always handle bulbs with gloves to avoid fingerprints and extend lifespan.

Q: Where can I attach a camera to the microscope, and what are the benefits of this feature?

A: A camera can be attached via the trinocular drawtube. This enables real-time image capture and documentation, supporting up to 5MP resolution and video at 1920x1080p (with an optional camera). It is especially beneficial for sharing observations, archiving data, and educational demonstrations.

Q: When should I use the provided color filters during microscopic observation?

A: Color filters (blue, green, neutral density) should be used to enhance contrast and image clarity depending on the sample type and observation needs. For example, a blue filter improves color correction in transmitted halogen light, while neutral density filters reduce light intensity without altering color balance.

Q: How do I ensure consistent and precise sample positioning on the stage?

A: The mechanical stage is rotatable and can be locked at any position using its secure locking mechanism. Graduated scale and vernier reading let you fine-tune the angle (up to 0.1 precision) for accurate, repeatable positioningcritical for detailed analysis or multi-view documentation.

Q: What maintenance procedures should be followed to prolong the life of the microscope?

A: Keep optics dust-free using included dust cover when not in use, clean lenses gently with lens paper, replace halogen lamps promptly, and ensure anti-slip feet are clean and stable. Periodically check and lubricate mechanical components according to the manufacturers instructions for optimal performance.
