Versatility in Petrological AnalysisEngineered for petrographic studies, the PQR-500IM enables visual and polarizing observations. Its rotating stage, vernier scale, and set of achromatic objectives deliver up to 1000x magnification, empowering users to examine mineral thin sections in detail. Bertrand lens and analyzer allow both orthoscopic and conoscopic techniques.
Robust Construction and Ergonomic DesignThe microscope's durable metal alloy frame resists corrosion, ensuring longevity in demanding environments. Ergonomic features include a monocular tube inclined at 45 and a 360 rotatable round stage for comfortable and flexible use during prolonged sessions.
Efficient Illumination and Fine FocusEquipped with a 6V/20W halogen lamp and adjustable brightness, the PQR-500IM delivers clear, evenly lit samples. Coaxial coarse and fine focus controls, along with adjustable tension, make it easy to achieve sharp imaging, crucial for distinguishing mineralogical features.
FAQ's of PQR-500IM Petrological Microscope:
Q: How does the graduated rotary stage with vernier improve angular measurement accuracy?
A: The graduated rotary stage with vernier allows users to make precise angular measurements of mineral sections, which is essential for identifying optical properties in petrographic analysis. The vernier scale enhances accuracy by providing fine subdivisions for detailed readings.
Q: What is the function of the Bertrand lens in the PQR-500IM microscope?
A: The swing-in/out Bertrand lens enables both conoscopic and orthoscopic views, allowing users to analyze interference figures and extinction angles in minerals. It's especially beneficial for advanced petrological studies that require detailed examination of optical features.
Q: When should I use the polarizer and analyzer during microscopy?
A: The polarizer (below the stage) and rotatable analyzer (above the objectives) are used for polarized light microscopy. Insert the polarizer and rotate the analyzer to examine birefringence, optical orientation, and other defining properties of geological samples.
Q: Where can I obtain spare parts for the PQR-500IM microscope?
A: Spare components such as eyepieces, objectives, bulbs, and fuses are available from your microscope supplier or manufacturer. Always refer to the user manual for part numbers and contact details for authorized distributors.
Q: What maintenance process is recommended for optimal performance?
A: Regular maintenance includes using the supplied cleaning cloth for optics, replacing the halogen lamp as needed, applying included immersion oil for high magnifications, and covering the microscope with the Dust Cover when not in use to prevent dust accumulation.
Q: How do I adapt the microscope for different voltages?
A: The PQR-500IM is compatible with AC 220V/50Hz as standard. If you require alternative voltages, specify your needs when ordering, and the manufacturer can provide the correctly adapted model.
Q: What benefits do coaxial coarse and fine focus controls provide for users?
A: Coaxial coarse and fine focusing enables smooth, precise adjustment of sample clarity and focal depth. This dual-control system helps users quickly locate features at low magnification and then achieve fine detail without shifting their hands or position.
