Optical Shutters

MEMS 0.3mm Movement Free Space Attenuator/Shutter Chip

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 ≤ 300 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. The different movement FS-VOA chip up to 700µm is available, please contact us.
