The SC-SYS-2S scanning 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. The two identical scanners are ONE FIXED FREQUENCY each, picked from the range of 10 Hz to 16 kHz. They are small size, light weight, low cost and long life devices. They require low power drive electronics and do not radiate any electromagnetic interference (EMI). The scanners have high amplitude stability and very low amplitude jitters; wobble is less than 1 arc sec. The scanners are IR, VIS, UV and high vacuum capable. Reference signal and position output available.
The PLD-2S driver phase locks two identical scanners. 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 requirements (0° to 360°) and is front panel adjustable in a range of ±45° min. The driver can be a fully integrated driver with front panel 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 board level printed circuit board level driver with the components but without the box and the power supply.
