Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3).It's a negative uniaxial crystal and mostly used as visible and near IR polarizers. It has high birefringence, wide spectral transmission and availability in reasonably sized rhombs.

Polarizing Beamsplitter Cubes are constructed by cemented two right angle prisms High Damage Threshold Coated for Laser line 355, 405, 532, 633, 780 - 808, 1064 nm or Broadband

Right Angle Prism is deviating or deflecting a beam of light with 90°or 180°. It is often used in telescope, periscope and other optical system. Deviate Beam or Image by 90° or 180° Material: N-BK7, UV Fused Silica, CaF2, ZnSe, or Ge AR-Coated, HR coated are Available

Dual Wavelengths Waveplate is a multiple waveplate that provide a specitfic retardance at two different wavelengths Operates as λ/2 @ λ1 & as λ/4 @ λ2 Dual Wavelength Operation 532 nm/1064 nm

LiNbO3 crystal is widely used as frequency doublers for wavelength > 1mm and optical parametric oscillators (OPOs) pumped at 1064 nm.
