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

Broadband and Narrowband Non-Polarizing Plate Beamsplitters
Non-Polarizing Plate Beamsplitters can be used with high power laser. When using beamsplitter plates, it is important to bear in mind that the two partial beams travel different optical paths. And the optical paths depend on the incident angle and the thickness of plates.

High Precision Optical Glass Penta Prisms
Penta prisms are five-sided prisms featuring a ray deviation of 90° and a right handed image 90° Deviation of Beam or Image Right Handed Image Coating are avaliable
Glued Prisms and Special Customized Prisms
Glued prisms are glued by different shape prisms. WTS offer Special Prisms like Half Penta Prisms, Pellin-Broca Prisms, Pechan Prisms etc. prisms
IR Windows Germanium Windows
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
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.
Fused Silica Windows and Quartz Windows
Fused Silica material Advantages With Good UV and IR transmission, Low thermal expansion, providing stability and resistance to thermal shock, Wider thermal operating range and High laser damage threshold make Fused Silica windows could used for Laser, Medical, imaging etc. application.
BK7 and Fused Silica Glass Schmidt Prisms
Schmidt Prisms Schmidt prisms are used to invert and revert an image to angle of 45°. The 45° deviation makes Schmidt prisms useful in eyepiece assemblies and imaging systems requiring a path bend. 1. Ray Deviation of 45° 2. Right Handed Image 3. Combine with Half-Penta Prism to Create Pechan Prism
