The chopper frequency refers to the on/off chopping frequency that can be generated by the wheel chopping a laser beam; it does not refer to the rotational speed of the chopper motor. For instance, the rotational speed of the chopper motor goes from a minimum of 2 rotations per second up to a maximum of 106.5 rotations per second. Therefore, the 2-slot wheel has a chopping frequency range of from 4 Hz to 213 Hz.
