The
variable beam attenuator enables a continuous attenuation
of the laser energy and is specially used for high-power
excimer lasers.The optic components of the device
consist of a dielectric filter for beam attenuation
as well as a neutral optical unit to compensate
the beam displacement. The continuous attenuation
of the coupled laser beam is attained by changing
the angle of incidence of the dielectric filter
in the range of 0¡Æ to 45¡Æ. The device is available
as hand-operated version with mechanical gear or
as motor-driven version together with the controller
model ML 2010 (see separate datasheet).
