The SC-2 fixed frequency resonant optical scanner is the smallest mechanical scanner available, according to manufacturer Electro-Optical Products.
It is an electromagnetically driven moving mirror device, which deflects a light beam with a continuous sinusoidal motion. The mirror assembly is attached at the centre of a taut band spring.
The scanning frequency range of the SC-2 type scanner is from 100Hz to 1,000Hz, 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 +55°C.
The scanner is suitable for dedicated, high volume, OEM industrial applications, and can be incorporated into very small systems and portable instruments.
