MEMS 0.7mm Movement Free Space Attenuator/Shutter With Mount
The etMEMS™ series of free space variable optical attenuator (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 FS-VOA is designed to completely block a collimated light beam over 700 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 and receiver systems.
It is available in either normally-open or normally-closed configurations.
