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

BBO Crystal is an efficient NLO crystal for the second, third and fourth harmonic generation of Nd:YAG lasers, and the best NLO crystal for the fifth harmonic generation at 213 nm.
Hastings triplets achromatic lenses are designed to provide an infinite conjugate ratio and are useful for focusing collimated beams and for magnification. Steinheil triplets achromatic lenses are designed to provide a finite conjugate ratio and 1:1 imaging.
Sapphire Windows Transmission in 0.3-5.0μm, no absorption in 2-3μm Extremely hard and durable High thermal conductivity High bulk damage threshold
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
Custom step windows are ideal use in viewports, pressure, and vacuum situations. Sapphire step windows also make great viewports for deep ocean vehicles.
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
