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

Potassium Dihydrogen Phosphate (KDP) (KH2PO4), Potassium Dideuterium Phosphate (DKDP ) (KD2PO4) are among the most widely-used commercial NLO materials, characterized by good UV transmission, high damage threshold, and high birefringence, though their NLO coefficients are relatively low. They are usually used for doubling, tripling and quadrupling of a Nd:YAG laser at the room temperature. In addition, they are also excellent electro-optic crystals with high electro-optic coefficients, widely used as electro-optical modulators, such as Q-switches, Pockels Cells, etc.
KDP&DKDP Crystal Advantages
1.Good UV transmission
2. High optical damage threshold
3. High birefringence High nonlinear coefficients

Optics Glass Micro Lenses Optics Glass micro lenses size are smaller than 3mm, which use for fibter, medical and laser etc. speciification. The shape could be achromatc lenses, plano-convex, meniscus etc. as micro lenses
30° - 60° - 90° Littrow Prisms
30° - 60° - 90° Littrow Prisms have two main applications. 1. Uncoated littrow dipersion prisms are used to disperse light into its component spectrum. 2. Coated littrow dipersion prisms are used to deviate the line of sight by 60°.
Optical Coated Bandpass Filters
Bandpass filters are allow special wavelength for transmission and block all other wavelength light.
High Precision True Zero Order Waveplates
True Zero Order Waveplates 1. Constructed of a true zero order waveplate and a BK7 substrate.As the waveplate is very thin and easy to be damaged,the Bk7 plate's function is to strengthen the waveplate. 2. Single Plate
