Brewster Optical Windows, Minor Axis=20.0mm, Major Axis=35.37mm, Thickness=2.0mm, Uncoated, UV Fused Silica, United Optical Technology Co., Ltd (CAT#: STEM-OP-3129-YJL)

Brewster Optical Windows, Minor Axis=20.0mm, Major Axis=35.37mm, Thickness=2.0mm, Uncoated, UV Fused Silica, model 197546, is manufactured by United Optical Technology Co., Ltd.
UV Fused Silica Brewster Windows take advantage of the material's total reflection properties. When light is incident at a specific angle of incidence (called the Brewster angle of the material), the S polarized component of the incident light is partially reflected, while the P component is nearly completely transmitted.
Brewster windows are suitable for applications where linearly polarized light is obtained.

UV fused silica glass material has a wider spectral range (185nm-2.1μm) than K9 optical glass and has excellent transmittance in the ultraviolet band. It has a lower refractive index, better uniformity, smaller thermal expansion coefficient, higher chemical resistance and very low fluorescence. It can be used to make various optical components, such as lenses, windows, filters, beam splitters, reflectors, prisms, etc.
