The PLD-1S driver phase locks any resonant scanner (type SC, except for the subminiature scanners) to an external clock signal, to provide an ultra stable scanning beam motion [sub] system. The system can be used as a "stand alone" unit, in the laboratory, or can be incorporated into a larger instrument/system. The scanner is ONE FIXED FREQUENCY, picked from the range of 5 Hz to 20 KHz. The scanner is a small size, light weigh, low cost and long life device. It requires low power drive electronics and does not radiate electromagnetic interference (EMI). The scanner has high amplitude stability and very low amplitude jitters; wobble is less than 1 arc sec. The scanner is IR, VIS and UV and high vacuum capable. Reference signal and position output available.
Although the scanner can be used in a large temperature range this driver is not recommended for use in temperature sensitive applications. To lock the scanner to an external clock signal you need to specify the exact clock frequency (to 4 decimal places). The phase relationship to the clock is factory set to customer's requirements (0° to 360°).
The PLD-1S-110 or PLD-1S-220 driver is a boxed driver for 110V or 220V (please specify). The driver has front panel controls for amplitude and phase and internal power supplies. The dimensions of the cased driver are: 12" × 10" × 3.8"
The PLD-1S-110/220 is a boxed driver with a line switch selector for operating from a line voltage of 110Vac or 220Vac.
The PLD-1S-PC driver is a printed circuit board level driver which requires an external +/-15V DC power supply.
The phase relationship to the clock is factory set to customer's 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 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-1S-PC driver is a printed circuit board level driver which requires an external ±15V DC power supply.
