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
Retroreflectors (Corner Cube Prisms) reflect an image or beam back toward its original direction via three total internal reflections (TIR)

T/T Payment, Western UnionCorner Cube Prism also called Retroreflector. It has three mutually perpendicular surfaces and a hypotenuse face. Light entering through the hypotenuse is reflected by each of the three surfaces in turn and will emerge through the hypotenuse face parallel to the entering beam regardless of the orientation of the incident beam. For its special performance,it is often used to the distance measurement, optical signal process and laser.

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
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
Custom step windows are ideal use in viewports, pressure, and vacuum situations. Sapphire step windows also make great viewports for deep ocean vehicles.
Zero order waveplate are constructed of two multiple order waveplates which is designed to give a retardance of zero full waves, plus the desired fraction. 1. Zero Order Waveplates-Cemented by Epoxy 2. Zero Order Waveplates-Optically Contacted 3. Zero Order Waveplates-Air-spaced
Elliptical Shape Mirrors Made of by Fused Silica or N-BK7 Coated by Dielectric coating or metal (Al, Au, Ag)coating Shape could be customized
Alpha-BBO Crystals is 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.
