Laser Attenuator Module
Preliminary Specification

General Description – The Laser Attenuator Module provides linearized control of laser energy.  The attenuator may be adjusted from 0% to 100% with a shutter closure to insure no residual energy at 0% output.  An internal calibration and linearization function simplifies setup and calibration.  Attenuator modules can be connected together in a daisy chain providing independent control of energy in multiple wavelength systems.
