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

Non-Polarizing Cube Beamsplitters also called NPBS Cube is a more sophisticated type consisting of two right- angle prismscemented together at their hypotenuse faces.The cemented face of one prism is coated.Before cementing, with a metallic or dielectric layer having the desired reflecting properties, both in the percentage of reflection and the desired color. The absorption loss to the coating is minimal and transmission and reflection could be designed to 10%, 20%, 30%, 40%, 50% etc.

LiNbO3 and MgO-LiNbO3 Nonlinear Crystal
LiNbO3 crystal is widely used as frequency doublers for wavelength > 1mm and optical parametric oscillators (OPOs) pumped at 1064 nm.
Optical Glass Plano-Convex Lenses
Plano-Convex Lenses is best used where one conjugate point (object distance S or image distance S' ) is more than five times the other. This lens shape is near best-form for either focusing collimated light or for collimating a point source.
Optical Glass Plano-Concave Lenses
Plano-Concave Lenses have a negative focal length and is typically used to cause a collimated beam to diverge as in a Galilean type beam expander or Telescope. 1. Beam expansion 2. Light projection 3. Expanding an optical system’s focal length
High Presion Optical Step Windows
Custom step windows are ideal use in viewports, pressure, and vacuum situations. Sapphire step windows also make great viewports for deep ocean vehicles.
