PC 4000 is the multi channel version of PC 1300, Motorized Polarization Controller. In addition to its basic function of adjusting polarization states in multi channels, it also provides convenient “save and recall” function that is memorizing angular positions of all waveplates to recall, and, as a Scanning PC, very powerful “auto scan” modes with variable scanning speed. Polarization states can be manipulated by either manual adjustment or remote control (GPIB&RS-232) using two quarter-wave plates in each channel of PC 4000.
