Page 3 - 40-20 scratch-dig Flat Windows

Uncoated sapphire provides exceptional surface hardness and a transmission range extending from the UV to the MIR. It can only be scratched by a few materials other than itself. The uncoated substrate is chemically inert and insoluble to water, common acids, or alkalis at temperatures up to ~1,000 °C. Sapphire windows are ...

Parallel Windows are similar to Plane Windows, but with parallel surfaces. These windows are well suited for applications in which angular deviation of the transmitted beam must be kept as small as possible. Misalignment errors are also minimized when the window is repeatedly inserted and removed. Round, square, and rectangular ...

Plane Windows are used as substrates for a variety of applications, such as laser windows, output couplers, beamsplitters, beam combiners, mirrors, dichroic filters and plate polarizers. Considerations in selecting window substrates include transmission range, absorption coefficient, incident laser power density and environmental ...

Windows are used to isolate different physical environments while allowing light to pass. The selection of a window should consider the properties of the different optical materials, transmission, wavelength range, and resistance to the environment. Tower offers a wide range of different materials and a variety of anti-reflecting ...
