Portable Optical Profilers

Optical profilers from 4D measure surface roughness and defects on smooth and supersmooth surfaces. Using Dynamic interferometry techniques exclusive to 4D, these profilometer measurements are non-contact and immune to vibration. The instruments are extremely portable and are able to perform surface profiling in the most challenging environments, at production speeds.

NanoCam Sq Optical Profiler

The NanoCam Sq non-contact optical profiler measures surface roughness on supersmooth optics and precision surfaces. The NanoCam Sq is a movable optical detection unit that can be positioned by hand or robotically. The compact and lightweight measurement head is highly flexible and can measure roughness anywhere on large optics, mirror segments or small optics.

The NanoCam Sq optical profilometer utilizes Dynamic Interferometry® and, because the acquisition time is so short, the NanoCam Sq can measure despite vibration.

InSpec Surface Gauge

The 4D InSpec Surface Gauge is the first handheld, precision instrument for non-contact surface defect measurement. With micrometer-level resolution, portability, affordability and ease-of-use, 4D InSpec instantly quantifies defects such as pits, scratches, nicks, dents and bumps, and measures features such as edge break, radii, rivet depth and dot peen depth, from 5 µm o 9 mm deep/tall. 4D InSpec is far more repeatable and accurate than visual comparison techniques typically used for surface defect measurements. And unlike high-end metrology systems it is rugged, flexible and affordable, to measure a wide range of part geometries in the most challenging environments.
