Optical Non-contact Profilers

Optical non-contact profilers assess nanoscale height differences on a surface with a high degree of precision. Based on the known wavelengths of light, optical non-contact profilers can measure a sample in three dimensions.

Optical profiling allows for the measurement of a surface's finish, roughness, and shape, as long as enough light is reflected back into the profiler’s objective from the sample. Some optical non-contact profilers may be limited with regards to measuring very high slopes, where the light is reflected away from the objective, except if the slope has sufficient texture to mirror light back to the objective.

These devices are used in many instances where micro-measurement of surface variations are required. Industries like optics and data storage use highly refined surfaces that are assessed with interference profilometers.
