Optical Shutters

High Speed Fiber Optical Sensor Protector

The optical power regulator, based on a high-performance variable fiber optical attenuator and high-precision control circuits, provides tunable optical output power and maintains it to counter the power fluctuations caused by PDL and other sources. The optical power regulator is designed to meet the most demanding operation requirements of ultra-high reliability and fast response to provide the ultimate solution for optical power stabilizing and limiting. Our also offers customized and embeddable electronic designs to meet special control applications.

MEMS 0.26mm 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, large shutter movement, simple construction, and direct drive. The et MEMS ™ series of FS-VOA are designed to completely block a collimated light beam ≤ 260 µm in diameter and to be operated in air without the need for a hermetic seal. They are 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 700 µm is available, please contact us.
