Dr.Gassler Electron Devices manufactures its RHEED Screens on its own production line. Not only standard sizes, but almost all formats and specialities can be realized within short terms.

Our screens are manufactured with a serigraphic printing machine either on Borosilicate glass Bor33 or on X-Ray protection glass RD50. Therefore typically no additional X-Ray protection glass is needed in front of your MBE view port.

For conduction we can provide a direct ITO coating on the glass or an aluminium coating on the back of the phosphor. This aluminium back coating yields in a significant higher light output to the viewer. All light which otherwise would be lost towards the vacuum chamber gets immediately reflected to the viewers direction. Additionally all light produced in the chamber from glowing substrates or elsewhere, is blocked by the optical dense aluminium coating, resulting in a much better contrast. 

Our RHEED screens are individually boxed and protected between 2 spherical glass plates to avoid any damage during shipment and storage.

Please see below our list of standard RHEED Screens. If you do not find your type of screen, just send us the details of the screen you are looking for.
