CO2 Laser Window WZ-0.75-3
Protective windows isolate physical spaces while allowing a light beam to pass through. When selecting a window, consider the material, transmission, divergence, wavefront error, parallelism and stability in the intended environment. SPT Laser offers a variety of windows made from different materials, as well as windows with single-layer or multilayer antireflection coatings.

Diameter: 10 mm to 127 mm Diameter Tolerance: +/-0.02mm Material: JGS1
The Brewster window uses the material's total-reflection properties. At the specified incidence angle, known as the material's Brewster angle, the S-polarized component is partially reflected while the P component is nearly fully transmitted. Sunday offers various UV fused-silica Brewster windows for ultraviolet applications.

An optical dome is a lens element with two concentric spherical surfaces. Common materials include K9 glass, fused silica, ZnS and ZnSe, with parallelism tolerance controlled within 2μm. Typical shapes are hemispherical or hyperhemispherical. Widely used in detectors, optical sensors, underwater photography and security monitoring, domes protect internal optics, provide a wide-angle light-entry window and optimize optical transmission.

For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift.
