SC-5 Mini Resonant Scanner Description:

Datasheet

The SC-5 type sub-miniature fixed frequency resonant optical scanners are electromagnetically driven moving mirror device, which deflects a light beam with a sinusoidal motion. The mirror assembly is attached at the center of a torsion spring. The scanning frequency range of the SC-5 type scanner is from 100 Hz to 1500 Hz, fixed at any one value within the range. The scan angle is inversely proportional to the frequency, and is a function of the mirror size. The standard operating temperature is 0°C to +65°C. Other temperature range and vacuum operation are available upon request.

High device "Q" insures frequency stability, low reaction forces and low electrical drive power. High flexural stiffness provides good resistance to shock and vibration, as well as low wobble, and good scan repeatability. Resonating at the natural frequency makes the device an excellent candidate for long life operation for a multitude of applications which require good imaging with minimal distortion. The scanner is especially suitable for dedicated, high volume, OEM industrial applications. The SC-5 type scanner can easily be incorporated in small size and portable instruments.

Operation at resonant frequency is sustained by a feedback amplifier type ED driver or the AGC driver, using the scanner as a frequency source. The AGC driver also provides a higher amplitude stability (0.01%) and a position output signal. The PLD-1S driver phase locks the scanner to an external clock signal. The PLD-2S driver locks two scanners of the same frequency in a Lissajous pattern to create a circle or an ellipse or to lock two resonant scanners of the same frequency in phase or out of phase. The PLD-2SXY driver locks two resonant scanners to generate a raster scanning system. The PLD-XYG driver locks a resonant scanner (high frequency) with a galvanometer (low frequency) to generate an X,Y raster scanning system.
