The Acuity AR200 laser measurement sensors project a beam of visible laser light that creates a spot on a target surface. Reflected light from the surface is viewed from an angle by a CMOS line scan camera inside the AR200 sensor. The target’s distance is computed from the image pixel data. The AR200 can not be overloaded and measures accurately even when a mirror reflects the entire light beam back to the detector. This measurement principle is called triangulation. The signals are processed digitally and output on an RS232 line or are converted to an analog signal.

Although the AR200 laser measuring tools use metric nomenclature, the spans are in fact quarter, half, one and two inches for the -6, -12, -25 and -50 models, respectively.

AR200 laser sensors are fast as well as accurate. The maximum sampling speed of the AR200 sensor is 1250 samples per second with a resolution of 0.03% of the measuring span. The AR200 is standard with many digital and analog outputs.

This Acuity model can only withstand temperatures to 50°C. Under some applicaiton circumstances, the AR200 laser measurement sensor can be used to measure to glass.
