ABSTRACT:
An electronically variable optical attenuator includes focusing optics that enable the use of a micro-mechanical actuation device with minute movement properties. The actuation device controls the position of a light blocking member relative to the path of a focused light beam to thereby control the attenuation of the light beam.
