LASER LINE SENSORS USED TO MEASURE THICKNESS FROM 2 SIDES

An Acuity customer is using a dual opposed AP820 laser line configuration to be able to measure the thickness of a dark plastic sheet material. The uneven surface profile is used to calculate the overall thickness and make sure the material maintains a minimum thickness requirement.

The AP820 is very suited for difficult dark targets with its high dynamic range of the CCD chip in the sensor. Both sensors can be synchronized to make sure the measurements are very accurate.
