Optical Calcite Crystals
Birefringence: High birefringence, which allows for the separation of light into two orthogonal polarization states.
Transmission Range: Wide spectral range from 200 nm to 2500 nm.
Applications: Polarizing Prisms, Beam-Divergent Elements, Laser Gates, Group Velocity Delay Compensators, etc.
Optical calcite crystals are natural minerals characterized by their negative uniaxial crystal structure and significant birefringence across a broad transmission range from 200 nm to 2500 nm. Despite their relative softness and susceptibility to scratches, calcite crystals are highly valued for their optical properties and are used in a range of optical devices.
