20Kpps laser scanning galvo galvanometer scanner set ILDA

PRODUCT DESCRIPTION:

This is a fast and reliable scanner set based on a moving magnet galvanometer. In combination wit the small drivers and power supply unit this set can be implemented in almost any application. The speed is 20kpps (20.000 points per second) at an angle of 20 degree. By adjusting the potentiometers the speed can reach 35Kpps at an an angle of 5 degree.

THE MEASURING PROCEDURE:

This scanner set was measured with PANGOLIN QM2000 card. Running at the desired output speed. Using the standard ILDA test pattern. Laboratory power supply at +/-15VDC,room temperature. Windows PC with Pangolin,12/30k ILDA testframe, full size. 7x11x0.6mm mirror was used during measuring period. The galvos are fixed in the standard mounts on an aluminmum baseplate without forced cooling.

POTENTIOMETER DESCRIPTION:

• IS = Input scale (adjusted only in factory)
• SG = Servo gain (power of the feedback signal for internal PID controller
• LFD = Low frequency damping (correct overshoot)
• HFD = High frequency damping (correct undershoot)
• LIN = Zero offset (electrical offset of the driver, adjusted only in factory)
• PS = Position scale (increases or decrease input sensitivity of the computer, DO NOT change it)
