Optical Profiler
Mar 2016
Filmetrics Inc.Request Info
SAN DIEGO, March 2, 2016 — Optical ProfilerFilmetrics Inc. has announced the Profilm3D low-cost optical profiler, increasing the accessibility of profilometry equipment.

The device uses vertical scanning interferometry and phase-shifting interferometry to measure 3D surfaces with high accuracy. It can also measure surface features and roughness with subnanometer resolution.

Optical profilers are used to image manufactured surface features and investigate wear, fit, leaks, vibration and friction. Applications include use in the semiconductor, solar cell, optics, automotive and biomedical industries.

optical profiler
Also known as a white-light interferometer. Measures surface texture and shape from nanometer-scale roughness to millimeter-scale step heights. A standard arrangement includes an illumination source, traditionally a tungsten-halogen bulb, coupled to an optical system with a variety of interferometric objectives.
Measurement of surface roughness or quality through the use of a diamond-pointed stylus connected to a coil in an electric field. As the stylus is traced across the surface, a current is created that corresponds to the roughness.
