RMI Laser Optics and Coatings Prototype Through Production

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.
