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) 180° Reflection Inverts Image 3 arcsec Beam Deviation
Right Angle Prism is deviating or deflecting a beam of light with 90°or 180°. It is often used in telescope, periscope and other optical system. Deviate Beam or Image by 90° or 180° Material: N-BK7, UV Fused Silica, CaF2, ZnSe, or Ge AR-Coated, HR coated are Available
Sapphire Windows Transmission in 0.3-5.0μm, no absorption in 2-3μm Extremely hard and durable High thermal conductivity High bulk damage threshold
KTP crystal is mostly used as nonlinear crystals for frequency doubling of solid-state Nd:YAG crystal or Nd:YVO4 crystal laser, as it has large nonlinear optical coefficients, wide angular bandwidth and small walk-off angle, broad temperature and spectral bandwidth.
Glued prisms are glued by different shape prisms. WTS offer Special Prisms like Half Penta Prisms, Pellin-Broca Prisms, Pechan Prisms etc. prisms
