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

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3).It's a negative uniaxial crystal and mostly used as visible and near IR polarizers such as Glan Taylor, Glan Thompson and Glan laser. It has high birefringence, wide spectral transmission and availability in reasonably sized rhombs.

Optical glass micro lenses and small size lenses
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
KDP&DKDP Nonlinear Crystal
KDP&DKDP Crystal are commonly used for doubling, tripling and quadrupling of Nd:YAG laser at the room temperature.
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°.
High Accuracy Glass Pyramid Prisms
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.
