Technology type: Galvanometer Scanners and Shutters

The application areas of these fast Uniblitz shutters are manifold and range from the modulation of light in general and laser radiation, in particular to exposure protection of detectors or camera sensors and the blocking of X-rays.

The LS and VS Uniblitz series are optimised for high shutter speeds, so that minimum window times can be used for laser applications or short exposure times for detectors and cameras. A large selection of materials for the shutter blades allows use with intensive laser power from deep UV to infrared. In addition, special PtIr blades are available for blocking X-rays. The Uniblitz shutters can be used both under normal conditions and with special encapsulation of the drive coil in a vacuum. For fail-safe use, the shutters can be divided into unistable and bistable shutters. The unistable versions, which include the types LS, VS, FS, and CS, close passively by means of a return spring, whereby the bistable shutters each require an electrical pulse for closing and opening and do not need electric power to hold in position.
