Advanced Dual Illumination Infinity-Corrected Polarizing Light Trinocu – AmScope

The PZ620T is an upright polarized-light microscope with transmitted and refelcted 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 retardationplates are incuded 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.
