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
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

Optical Gold Coated Mirrors Average Reflectance >94% from 800 nm to 20 µm Shape could be customized: Round, Square, Elliptical, Right angle prisms Material could be customized: Fused silica, Pyrex, N-BK7
Rhomboid prisms are commonly used to displace a laser beam without changing its direction. Lateral Displacement of Beam Displaces Optical Axis Without Inverting Image
Bandpass filters are allow special wavelength for transmission and block all other wavelength light.
Dielectric Mirrors offer near total reflection, minimizing losses in nearly all optical systems. AOI=45°, R>99.5% (Rs>99.9%, Rp>99.2%). AOI=0°, R>99.8%
