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 Precision Glass Equilateral Prisms and Dispersing Prisms
Equilateral Prism has three equal 60°angles, and are mostly used to disperse the spectrum.
BK7 and Fused Silica Glass Dove Prisms
Dove Prism has two applications. 1. The main application is used as a rotator. 2. Another application is used as a retroreflector.
BK7 and Fused Silica Glass Schmidt Prisms
Schmidt Prisms Schmidt prisms are used to invert and revert an image to angle of 45°. The 45° deviation makes Schmidt prisms useful in eyepiece assemblies and imaging systems requiring a path bend. 1. Ray Deviation of 45° 2. Right Handed Image 3. Combine with Half-Penta Prism to Create Pechan Prism
High Precision Zero Order Waveplates
