Transflective Polarizing Microscope (Trinocular), LWT150PT

Instrument use: 

LWT150PT transflective polarized light microscope, using polarized light to study the strength of inhomogeneous medium and identification of various differences, mainly used for the observation and research of its birefringent crystal, for the analysis of the optical properties of rock ore and textile fiber Special effects. In addition, the LWT150PT has become a necessary tool for scientific research, college testing, and teaching because of the increased camera function, image processing and software qualitative and quantitative analysis technology, and is applied to the identification and verification of product quality in related industries.
