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

Cut-Off Colored Glass Filters is named based on spectral characteristic of which is represented by the wavelength transmission limit. For example, if the transmission limit of glass is 490nm,then it is named as JB490. It separated to Long Pass Color Glass filters and Short Pass Color Glass filters. There are five groups and 35 types glasses. The Following are the 35 Types Glasses
Their main application are as below:
1. Environmental displays
2. Optical metrological instruments
3. Laser protective windows
4. Machine vision devices
5. Optical detection instruments
6. Optical test instruments
7. Electro-optic displays
8. Medical optical

Selective Absorption Colored Glass Filters This part of the glasses can be divided into 14 kinds and 78 types based on the color and application in this catalogue.
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%.
Double Convex Lenses, Bi-convex Lenses have two outward curved surfaces, a positive focal length and are useful for 1:1 imaging and in multi-element systems.These lenses are designed to have a focal length of f= (R1*R2)/((n-1)*(R2-R1)) 1. Supported by the Zemax Optical Design Package 2. Posistive Focal Length 3. Material upon requirement
Pyramid prisms has a base that is connected to a single vertex, not in the same plane as the base, by line segments from each vertex of the base shape.
Alpha-BBO Crystals is high temperature phase of BaB2O4 is an excellent birefringent crystal; it is characterized by large birefringent coefficient and wide transmission window from 189nm to 3500nm.
BBO Crystal is an efficient NLO crystal for the second, third and fourth harmonic generation of Nd:YAG lasers, and the best NLO crystal for the fifth harmonic generation at 213 nm.
