Scan Speed

The scan speed is specified in pps (points per second) or kpps (kilo points per second) and is used to describe how fast the mirrors of a scanning system move to produce an output image by deflecting the beam. The maximum scan speed of a show laser depends on the quality of the scanning system used. The higher the scan speed, the higher the resolution of the laser graphics.

The possible maximum scan speed depends on the actual scan angle. For graphic projections, a minimum of 25 kpps @ 8° ILDA is recommended. For beam shows, a slower scan speed will usually do the job.

In addition to the scan speed, the quality of a laser output also depends on several different scan parameters, including point repetitions, output optimization as well as the motor performance depending on the scan angle.
