NP-400/NP-400M/NP-400P
Polarizing Microscope
Description
Polarizing microscope NP400 can observe mineral crystal figure, color and interference color and also identify its optical performance. It is a good microscope used in geology, petroleum, coal, Chemical fiber, medical treatment and physic inspection. It is also widely used in academic demonstration and research.
