Calcite Crystal Used In Polarization Devices
Calcite crystal is a kind of natural birefringent material, which has good optical properties in near infrared. Calcite crystal is widely used in polarization devices because of its large size and low price.
Application: Gran prism, polarization beam splitter, etc.
