MEMS 0.3mm Movement Free Space Attenuator/Shutter With Mount

Enquire Now

The MEMS series FS VOA is based on a proprietary patent pending micro-electro-mechanical mechanism featuring exceptionally compact size with large shutter movement, simple construction, and easy direct drive. The MEMS series FS VOA is designed to completely block a collimated light beam over 300 mm in diameter and be operated in air without the need for hermetic seal and is fully compliant with the Telcordia 1209 and 1221 reliability standards. The device is ideally suited to be integrated into laser systems.
It is available in either normally-open or normally-closed configurations.
