The PLD-2S driver phase locks two identical scanners. The [sub]system consists of two identical resonant optical scanners (type SC), Scanner "A" and scanner "B", in a MASTER/SLAVE mode, to provide ultra stable scanning beam motions. The system can be used as a "stand alone" unit, in the laboratory or as a portable instrument, or incorporated into a larger instrument/system.

Scanner "B" is phase locked to scanner "A" (the slave is locked to the master). The phase relationship to the master is factory set to customer requirement (0° to 360°) and is front panel adjustable in a range of +/-45° min. The driver can be a fully integrated driver with front panels controls and internal power supplies or a printed circuit board level driver. The dimensions of the cased driver are: 12" × 10" × 3.8". The PLD-2S-PC driver is a printed circuit board level driver, which requires an external +/-15V DC power supply.
