MEMS Straight Multimode MEMS Shutter / VOA

(high attenuation up to 65dB)

The etMEMSTM Straight Series multimode shutter/VOA is based on a proprietary MEMS design, offering many desirable features.  The MEMS shutter is capable of totally blocking the light, providing exceptionally large extinction.   It has no optical coating or lens, enabling broad wavelength operation, as well as high power capability.  This device is also low cost.

The shutter/VOA is driven with an electrical current at low voltage, and the attenuation can be continuously adjusted with the applied current or voltage. The silicon MEMS device is highly reliable with longevity.  However, it can be damaged by applying voltage over the threshold.
