The Compact-506 is a galvanometer-based optical scanning system, intended for applications where small package size, low cost, and light-weight are paramount concerns. Although the Compact-506 is very small, it is built upon our VRAD-506 actuator platform, and features a very strong construction and 6mm bearings. This construction allows the Compact-506 galvo to move small mirrors, as well as large mirrors (up to 1-inch in diameter) very easily, without a notch filter in the servo.
