1、 The purpose of the instrument:

The YPV-500 transmission reflection polarizing microscope is the most commonly used experimental instrument in departments such as geology, mineral resources, metallurgy, and related higher education institutions. It can be used for single polarization observation, orthogonal polarization observation, cone light observation, and microscopic photography by a wide range of users. It is equipped with accessories such as gypsum λ, mica λ/4 test pieces, quartz wedges, and moving rulers, such as chemical fibers for chemical industry, semiconductor industry, and drug inspection.

2、 Instrument features:

The reflective polarizing microscope system is a high-tech product that combines optical microscopy technology, photoelectric conversion technology, and computer image processing technology. Real time dynamic images can be easily observed on the display screen, and the required images can be edited, saved, and printed.
