Made from BK7 material, which has transparent range from 330-2100nm. The refractive index is 1.5168 at 587.6nm. The BK7 window has good performance over visible and near IR spectrum for most application.
Achromatic Waveplate Achromatic Waveplates(Retarders), AWP is composed of one piece of Crystal Quartz and one piece of Magnesium Fluoride, MgF2.
Barium fluoride (BaF2) shows good optical transmission over UV-IR windows in 0.15μm~12.5μm.
MgF2 windows are used in the UV, visible and IR ranges, with approximately 94% transmission from 200 - 1000 nm, and approximately 95% transmission from 1-6µm
CaF2 has transparent range from 170-7800nm. The refractive index is 1.399 at 5000nm. 1. Low absorption coefficient 2. High damage threshold, 3. Low Dispersion (with an Abbe Number of 95) 4. Low fluorescence 5. Excellent water, chemical, and heat resistance
ZnS is used widely for IR components, windows and lenses, and applied for Thermal Imaging, long-wave infrared sensors.

Zinc Sulfide (ZnS) is grown by chemical vapor deposition(CVD) method. It exhibits exceptional fracture strength and hardness leading to its frequent choice for military applications or other harsh environments. It is often used in the range of 3-5um and 8-12um. MultiSpectral grade ZnS(MS) is treated after growth to eliminate microscopic voids and efects which occur in the regular grade ZnS, thus extending the usefulness of this material to the visible region.
WTS offer CVD ZnS and Cleartran ZnS material windows, lenses etc. products.
