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

Barium fluoride (BaF2) shows good optical transmission over wide spectrum range, which can be used as UV-IR windows in 0.15μm~12.5μm. It also presents excellent scintillation properties, which is widely used in high energy physics, nuclear physics and nuclear medical instruments.
WTS make customized coated and uncoated BaF2 windows.
Note:When handling BaF2, please always wear gloves as it is a hazardous material.

30° - 60° - 90° Littrow Prisms
30° - 60° - 90° Littrow Prisms have two main applications. 1. Uncoated littrow dipersion prisms are used to disperse light into its component spectrum. 2. Coated littrow dipersion prisms are used to deviate the line of sight by 60°.
IR Windows Zinc Sulfide ZnS Windows
ZnS is used widely for IR components, windows and lenses, and applied for Thermal Imaging, long-wave infrared sensors.
YVO4 Birefringent Crystal
Undoped YVO 4 crystal is widely used in many beam displace online_orderings because of its large birefringence.
High Precision Calcite Birefringent Crystals
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.
