Optical Shutters

MEMS 0.5mm Movement Free Space Attenuator/Shutter With Mount

The et MEMS ™ series of free space variable optic 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 et MEMS ™ series of FS-VOA is designed to block a collimated light beam completely ≤ 400μm in diameter and be operated in the 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 for integration into laser systems. The different movement FS-VOA chip up to 700μm is available.
