Alkor MgF2 Windows
Magnesium Fluoride (MgF2) windows offer excellent broadband transmission from the deep-UV to the mid-infrared. DUV transmission makes them ideal for use at the Hydrogen Lyman-alpha line and for UV radiation sources and receivers, as well as excimer laser applications. Often used as UV viewports. Standard orientation of the crystal is ...

Sapphire Window
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 ...

RMI Parallel Windows - ZnSe - ZnS - Ge - Si - Cleartran - Chalcogenide Glass
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 ...
