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

Barium fluoride (BaF2) shows good optical transmission over wide spectrum range, which can be used as UV-IR windows in 0.15μm~12.5μm. It also presents excellent scintillation properties, which is widely used in high energy physics, nuclear physics and nuclear medical instruments.
WTS make customized coated and uncoated BaF2 windows.
Note:When handling BaF2, please always wear gloves as it is a hazardous material.

High Precision Glass Equilateral Prisms and Dispersing Prisms
Equilateral Prism has three equal 60°angles, and are mostly used to disperse the spectrum.
Optical Gold Coated Mirrors
Optical Gold Coated Mirrors Average Reflectance >94% from 800 nm to 20 µm Shape could be customized: Round, Square, Elliptical, Right angle prisms Material could be customized: Fused silica, Pyrex, N-BK7
High Precision Glass X-Cube and RGB Prisms
X-Cube (RGB Prism) Used under any polarization state High brightness Excellent White balance
N-BK7 and Fused Silica Wedge Prisms and Wedge Windows
Wedge Prisms (Wedge Windows) are ideal for laser beam steering applications. Also known as Risley prisms, these optics deflect a beam normal to the prism's perpendicular surface through an angular deviation.
The Most Hard Material Windows Sapphire Windows
Sapphire Windows Transmission in 0.3-5.0μm, no absorption in 2-3μm Extremely hard and durable High thermal conductivity High bulk damage threshold
High Precision Low Order Waveplate
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.
