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

High temperature phase of BaB2O4 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 α-BBO crystals are similar to those of β-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.
α-BBO is an excellent crystal to replace Calcite, TiO2, and LiNbO3, etc. in Glan-Taylor and Glan-Thompson polarizers as well as walk-off beam splitters, especially for high power and UV polarizer, due to its unique UV transparency, good mechanical properties and high damage threshold.

High Precision Glass Equilateral Prisms and Dispersing Prisms
Equilateral Prism has three equal 60°angles, and are mostly used to disperse the spectrum.
Optical Coated Bandpass Filters
Bandpass filters are allow special wavelength for transmission and block all other wavelength light.
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.
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°.
Triplet Achromatic Lenses
Hastings triplets achromatic lenses are designed to provide an infinite conjugate ratio and are useful for focusing collimated beams and for magnification. Steinheil triplets achromatic lenses are designed to provide a finite conjugate ratio and 1:1 imaging.
N-BK7 and Fused Silica Wedge Prisms and Wedge Windows
Wedge Prisms (Wedge Windows) are ideal for laser beam steering applications. Also known as Risley prisms, these optics deflect a beam normal to the prism's perpendicular surface through an angular deviation.
