The Lasercheck® line of laser-based surface roughness gauges offer precise non-contact surface roughness (Ra or RMS/Rq) measurement for portable or on-line use in a wide variety of manufacturing environments. Easy to set up, calibrate and operate, Lasercheck® provides fast and accurate surface measurement down to as smooth as 1 microinch (0.025 microns) in a fraction of one second.

Lasercheck® sensors are more rugged than other tactile surface roughness sensors and can be used in difficult manufacturing environments to perform high-volume quality control work, thereby freeing up stylus and optical profilometers to perform audit and process development measurements in a protected lab environment.

Lasercheck® sensors are optimized for surface measurements of ground, sanded, polished, honed, super-finished, and shot blast surfaces. These non-contact devices are Ideal for inspection of surfaces such as silicon for solar applications, rolls of any size, rods, bars (including surgical guide wire), sheet metal, and surface-critical automotive components such as camshafts, crankshafts, valve parts, brake & pump pins, and numerous steering, driveshaft, and suspension pins and shafts.

Compared to any alternative metrology technology, patented "light scatter" detection photonics provides superior durability, measurement speed and repeatability.
