2. Operation Principle PowerXP Maxi incorporates a rotating quartz λ/2 phase waveplate and one or two polarizers or polarizing cube which separate s-polarized and p-polarized beams (fig. 1). The intensity ratio of the two beams may be continuously varied without alteration of other beam parameters by rotating the waveplate. -

If your device is not calibrated all controls will be disabled. To calibrate your device, go to “Calibration” tab. - Page 12 Figure 6. Calibration tab. Calibration procedure: To correctly change the output power, the software needs to know the angle of the λ/2 waveplate’s fast axis. It can be fixed in any angle with respect to the rotator. The purpose of calibration is to fix angular offset between the λ/2 waveplate and the rotator hardware zero position.
