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

Low Order Waveplate (Multiple order waveplates) are made from a single crystalline plate, are designed to give a retardation of several full waves, plus the desired fraction. Low Order Waveplate are more susceptible to change in wavelength and they should not be used more than several nanometers outside of design wavelength.

KTP crystal is mostly used as nonlinear crystals for frequency doubling of solid-state Nd:YAG crystal or Nd:YVO4 crystal laser, as it has large nonlinear optical coefficients, wide angular bandwidth and small walk-off angle, broad temperature and spectral bandwidth.
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
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. It has high birefringence, wide spectral transmission and availability in reasonably sized rhombs.
Positive meniscus lenses is convex-concave lens thicker at the center than at the edges, which frequently used for beam focusing applications. Negative meniscus lenses is convex-concave lens thinner at the center than edges, which frequently used for beam expanding applications.
Germanium Windows are applied for IR Wavelength 1. 3 - 5μm for mid-infrared applications 2. 3 - 12μm for broadband multispectral applications 3. 8 - 12μm for thermal imaging applications
Achromatic Lenses (Doublets) VIS 0° and VIS-NIR coated achromats are also available Correct for on-axis spherical and chromatic aberrations Custom Achromatic Lenses Available
