New LED Technology Replaces the Laser Scan Micrometer

 

Old Principle

A semiconductor laser is fired at a rotating polygon mirror and scans through the measurement range. Measured values are calculated by measuring how long the laser is obstructed by the target.

New Principle

Green-LED light is emitted as a uniform collimated beam. The CMOS sensor accurately detects the position of the edge between light and dark edges of the received light and determines the measured values.

Advantage: The new LED principle leads to longer up-time and low cost-of-ownership without sacrificing performance.
