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

Low Order Waveplate (Multiple order waveplates) are made from a single crystalline plate, are designed to give a retardation of several full waves, plus the desired fraction. Low Order Waveplate are more susceptible to change in wavelength and they should not be used more than several nanometers outside of design wavelength.

Titanium-doped Sapphire(Ti3+:Al2O3)crystals combine supreme physical and optical properties with broadest lasing range which is most widely used crystal for wavelength tunable lasers.
Rod lenses Light pipes is used in the fields of medical, electronic, information, agriculture, communication and etc. 1.All surfaces (end-faces and cylinder)polished; 2.Only end-faces polished; 3.Only Cylinder polished.
Bandpass filters are allow special wavelength for transmission and block all other wavelength light.
Custom step windows are ideal use in viewports, pressure, and vacuum situations. Sapphire step windows also make great viewports for deep ocean vehicles.
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.
