Although crystal quartz is made of SiO2, it is different from fused silica, it is a positive uniaxial birefringent crystal. It features its very small birefringent refractive index difference, so it is always used in waveplates and other ...

CaF2 is a cubic single crystal. It has good transmission from UV to middle infrared wavelength. It is always used in excimer laser components. While, it is a little hygroscopic and susceptible to thermal shock. Transmission Range: ...

MgF2 is a tetragonal positive birefringent crystal. MgF2 has good chemical, mechanical and thermal characteristics compared with CaF2. Due to its high vacuum UV transmission and high damage threshold, MgF2 is usually used in VUV and excimer ...

Sapphire is a single crystal aluminum oxide (Al2O3). Its Mohs hardness is 9, it is one of the hardest materials. Sapphire has good mechanical strength, and it is also transparent from visible to IR spectrum. So, it is always used as window ...

Silicon is a good IR material , it can be used from 1.2 to 7 microns, its peak transmission range is in 3-5 micron. Silicon can be used in some circumstances where weight is a concern as that the density of Silicon is similar to optical ...

BBAR coating - is a multilayer dielectric antireflection coating made at specified wavelength range. Standard coating is designed to reduce reflection losses at input side over 1.1-1.2 micron range and output side over 2.6-11 micron range. Typical ...
