Research Polarizing Microscope is principal piece of equipment used by the Geologists to observe the optical properties of minerals. It has indispensable applications for petrography, crystallography, geology, mineralogy, ceramics, toxicology, chemical microscopy or detecting defects in semi-conductors, finding stress points in metals, glass & textiles etc
Stage - Compact Ball bearing Rotating Stage, 140mm dia., graduation with vernier, lock & stage specimen clips.
The PZ620T is an upright polarized-light microscope with transmitted and reflected light, and infinity-corrected, stress-free optics. Episcopic and sub-stage polarizers offer polarization of both light-sources, allowing this microscope to be used for metallurgical, mineralogical, and biological applications. The quintuple nosepiece with centerable ports can hold five of the seven included plan-achromatic objective lenses, which can be alternated depending on the application. The addition of a Bertrand lens allows easy viewing of conoscopic interference patterns. The analyzer features a full-range dial for adjustable cross-polarization. An assortment of retardation plates are included to further aid in analysis.
The graduated, circular stage provides 360° of rotation for birefingence-testing, as well as a mechanical caliper for X-Y translation.
