Research polarizing microscope

This Research Polarizing Microscope from Lafco is a 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.

Focusing: Coaxial focusing is provided with coarse tension adjustment ring and graduated slow motion knobs. Adjustable safety lock is attached to prevent the breakage of specimen slides.
