Straight Multi-Mode etMEMS VOA

The etMEMSTM series of straight multi-mode VOA is based on a proprietary etMEMSTM design, offering many desirable features. The etMEMSTM 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 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 etMEMSTM device is highly reliable with longevity. However, it can be damaged by applying voltage over the threshold.
