PM-320 TRF/PM-320 Series Polarizing Microscope are applied to differentiate component of matters that have refraction characteristic, as a sort of import tool in pharmacology, geognosy, metallurgy to research crystal, mineral, rock and metallurgical form. The instruments are adopted excellent UIS optical system, equipped with strain-free long working distance plan achromatic objective and wide field eyepiece. High precision rotatable polarizing stage and excellent accessories. They can be used in the mode that transmitted/ reflected to obtain nicer polarizing image. These products have good sculpt and steady mechanical structure, so that operate comfortable and expediently. They are the ideal instruments for factory, mine scientific research and university to check, research and teaching demo.
