2 Introduction
The Quantum Composers motorized attenuator module provides linearized control of
polarized laser energy. The attenuator may be adjusted from 0% to 100% with a shutter
closure to ensure no residual energy at 0% output. Internal calibration, linearization,
and anti-backlash functions simplify setup and control. The module is controlled via a
RS232 serial interface that can be daisy chained to other Quantum Composers laser
modules.
3 Setup
The motorized attenuator should be placed such that the laser beam is normal and
center on the input aperture of the attenuator. This will insure optimum extinction ratio.
Connections to the device for basic operation are listed in the electrical connections
section. At a minimum, power (5V and 12V) and RS232 (serial) connections are
required.
