RTS-DD Series rotary stages feature a compact, low profile design that helps minimize abbe errors when used in conjunction with another motion axis, and a brushless direct-drive servo motor that eliminates backlash and improves reliability by eliminating sliding friction throughout the stage. The series also features a high-resolution optical encoder with a precision index mark for homing, and a 30mm through-bore to enable the convenient routing of vacuum or high voltage lines for a wide range of wafer chucks.
They are ideal for use in a variety of laboratory, factory automation, and semiconductor processing applications, including: inspection, laser marking and machining, optical positioning, wafer alignment, and rate table, pan-and-tilt, and beam steering operations.
