Page 2 - lambda/4 Flat Windows

Used mostly for their very high hardness, sapphire optics are also used for their good transmission from UV to NIR. Due to the increase of actors in the sector, sapphire components prices decreased a lot in recent years, don\'t hesitate to challenge your current supply.  https://sinoptix.fr/sapphire/

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 ...
