  • High temperature phase of BaB 2 O 4 is an excellent birefringent crystal; it is characterized by large birefringent coefficient and wide transmission window from 189nm to 3500nm, particularly it is suitable to make the high power UV polarizer, due to its unique UV transparency and good mechanical properties. 

    The physical, chemical, thermal and optical properties of a -BBO crystals are similar to those of b -BBO, for instant high optical homogeneity (better than 1x10-6/cm), extremely low absorption in the UV to IR range (<0.5% from 300-2300nm), low hygroscopic susceptibility, high damage threshold. However, the nonlinear optical properties of a -BBO is vanished due to the centric symmetry with its crystal structure.
  • Calcite is a natural crystal that has high birefringence, wide spectral transmission and availability in reasonably sized rhombs. It's a negative uniaxial crystals and mostly used as visible and near IR polarizer.

  • LiNbO3 Crystal is widely used as frequency doublers for wavelength > 1 mm and optical parametric oscillators (OPOs) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices, due to its large Electro-Optic (E-O) and Acousto-Optic (A-O) coefficients.

  • MgF2 single crystal is a birefringent material with particular properties. It has a high resistance to mechanical and thermal shock and radiation. With wide transparent range and high transmissibility, it becomes a popular choice for VUV and excimer laser windows, polarizers, prisms, lenses, wedges, windows and other optical components.

  • Crystal quartz is a positive uniaxial birefrigent single crystal. Itioptics select the best quality quartz, which has min inclusions and refractive index variation as the raw material of our components. Quartz is commonly used for high damage threshold waveplate.
