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

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
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.
Selective Absorption Colored Glass Filters This part of the glasses can be divided into 14 kinds and 78 types based on the color and application in this catalogue.
Germanium Windows are applied for IR Wavelength 1. 3 - 5μm for mid-infrared applications 2. 3 - 12μm for broadband multispectral applications 3. 8 - 12μm for thermal imaging applications
Neutral Colored Glass Filters are named based on the average transmissivity characteristics in 400nm to 700nm wavelength with 2mm thick For example ZAB70 means 70%.
Custom step windows are ideal use in viewports, pressure, and vacuum situations. Sapphire step windows also make great viewports for deep ocean vehicles.
