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

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
Survey Prisms are for Surveying or land surveying is the technique, profession, and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them.
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%.
Retroreflectors (Corner Cube Prisms) reflect an image or beam back toward its original direction via three total internal reflections (TIR) 180° Reflection Inverts Image 3 arcsec Beam Deviation
Germanium lenses are perfect for Mid-Infrared(IR) applications 1. Excellent for Security, Military, and Imaging Applications 2. AR Coating Optimized for the 7 - 12 µm Range
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
