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

Plaon-concave cylindrical lenses are used to provide focusing power in one section only, For illumination or detection of light from line sources.Also used for anamorphic compression of beams and images. 1. Ideal for Applications Requiring Magnification in One Dimension 2. Used to Transform a Collimated Beam into a Line 3. Rectangular and Circular 1
Double Concave Lenses, Bi-Concave Lenses is like the Plano-Concave lenses in that they are used to produce divergent light. The Bi-Concave is best used when the input beam is converging. 1. Supported by the Zemax Optical Design Package 2. Negative Focal Length 3. Material upon requirement
KDP&DKDP Crystal are commonly used for doubling, tripling and quadrupling of Nd:YAG laser at the room temperature.
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.
Neutral Colored Glass Filters are named based on the average transmissivity characteristics in 400nm to 700nm wavelength with 2mm thick For example ZAB70 means 70%.
