Laser Beam Steering Correction System

GuideStar II from New Focus – a Newport Corporation Brand – is a Picomotor mirror-mount-based laser beam steering correction system. Providing high reliability and high precision control of laser pointing and position drift, the system includes two independent Picomotor-actuated, motorized mirror mounts to provide both manual and active 4-axis control with passive stability. There are two miniature CMOS cameras that provide position sensing and continuous tracking of both laser beam positions and laser beam profiles.
