BK-POL Transmission reflection transmission polarization microscopeDetailed product description：

BK-POL transmission reflection polarization microscope is an essential tool for studying and identifying substances with birefringence, suitable for observing and determining the physical and optical properties of crystals under single light, orthogonal polarization, and cone light. Widely used in research and inspection in fields such as geology, minerals, metallurgy, chemical engineering, medicine, and pharmaceuticals.
The polarizing microscope is equipped with a transmission (20W or 30W illumination) and reflection (50W illumination) illumination system, an infinitely distant stress free flat field objective lens, an adjustable intermediate converter, and an adjustable intermediate rotating platform. It is a high-performance polarizing microscope with complete functions and good quality.
