The MEMS series free space VOA is based on a patented micro-electro-mechanical mechanism featuring exceptionally large shutter movement and high reliability. The MEMS series free space VOA is designed to completely block a collimated light beam over 500 mm 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 to be integrated into laser systems. Its control is conveniently applying a voltage. High mechanical resonance shutters (smaller displacement) that are vibration insensitive are available. Temperature-compensated chip is an option. Below is a list of several versions well suited for evaluation. Many variations are not listed but are available upon request. With in-house wafer production, we are specialized in custom design meeting demanding requirements.
