Advance Polarization Microscope GeM

Advanced Polarizing microscopes are principal piece of equipment used by the geologists to observe the optical properties of minerals. In has indispensable applications for petrography, crystallography.geology or finding stress points in metal,glass and textiles, etc. It permits orthoscopically to examine and identify the structures of material with highly resolved distinctive images under various magnifications.

Stage – Compact ball-bearing centerable rotating stage, 140mm. diameter, graduated with vernier, lock & stage specimen clips
