摘要： A laser marking system for marking a predetermined pattern on a workpiece may include a first light source structured to emit first light at a first wavelength; a second light source structured to emit second light at a second wavelength different from the first wavelength and selected to mark a marking surface of the workpiece; beam shaping optics structured to adjust a focal length of the second light; beam steering optics structured to aim the first laser light and the second laser light; a controller configured to control the first light source to emit the first light at the marking surface of the workpiece and control the beam steering optics to aim the second light so as to mark the marking surface of the workpiece and create the first predetermined pattern; and a camera structured to detect first light reflected from the marking surface and record an image.

摘要： An actuator may include a stator supporting a magnet; a stationary pole; and a bobbin supporting a winding of a coil, the bobbin being coaxial with the stator and stationary pole, and positioned inside the magnet and outside the stationary pole. A gap may be provided between the bobbin and the stationary pole. A beam steering mechanism may include a mirror; a frame; a pivot anchor fixed to the frame and connected to the mirror; and an actuator. An output end of the actuator may be connected to the rear surface. A beam steering mechanism may alternatively include a flexure; a mirror attached to the flexure; a frame; supports fixed to the frame and the flexure; a pivot anchor fixed to the frame and connected to the mirror or the flexure; and an actuator. An output end of the actuator may be connected to the flexure.
