Optical Shutters

MEMS 0.26mm Movement Free Space Attenuator/Shutter With Mount

The et MEMS ™ series of free space variable optic attenuator (FS-VOA) is based on our proprietary patent pending micro-electro-mechanical mechanism featuring exceptionally compact size with large shutter movement, simple construction, and direct drive. The et MEMS ™ series of FS-VOA is designed to completely block a collimated light beam ≤ 260 µm in diameter and be operated in air without the need for a 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 coherent detection systems. It is available in either normally-open or normally-closed configurations.
