Can I use my electronic head with a different optical head?

No. The PEM is a resonant device, with the resonant frequency being determined by the size of the optical assembly. In spite of very tight manufacturing tolerances, each optical head is slightly different in size and this results in a slightly different frequency. The controller, electronic head, and optical head are all calibrated to work together as one resonant circuit. Changing the pairing of the electronic and optical heads would change this precise calibration and PEM performance can no longer be guaranteed. If you have further questions, please Contact Us.
