1、 The purpose of the instrument:

The YPV-900 series reflective polarizing microscope is the most commonly used professional experimental instrument in departments such as geology, mineral resources, metallurgy, and related higher education institutions. It can be used for ordinary 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, etc The transmission and reflection polarizing microscope can not only observe transparent substances, but also study the optical, physical, and chemical properties of metallic or non-metallic minerals, in order to identify minerals. It is an essential high-end polarizing microscope for studying transparent or opaque substances.
