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

Silicon Windows are used for 1.2-7um Available Uncoated or AR Coated for 3 - 5μm Ideal for Weight Sensitive Applications
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°.
Dual Wavelengths Waveplate is a multiple waveplate that provide a specitfic retardance at two different wavelengths Operates as λ/2 @ λ1 & as λ/4 @ λ2 Dual Wavelength Operation 532 nm/1064 nm
True Zero Order Waveplates 1. Constructed of a true zero order waveplate and a BK7 substrate.As the waveplate is very thin and easy to be damaged,the Bk7 plate's function is to strengthen the waveplate. 2. Single Plate
