Optical Profilers for Surface Finish Measurements

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 dynamic optical surface profilerThe NanoCam Sq optical surface profiler measures surface roughness on supersmooth optics and precision surfaces. The non-contact NanoCam Sq profilometer's vibration immune measurements vastly improve optical profiling versus the messy replication methods required with table-top workstation optical profilers—NanoCam Sq's portability is excellent for measuring large optics. It's a movable optical detection unit that can be positioned by hand or robotically, testing anywhere on the surface of an object too large to fit inside the viewing volume (or on top of the positioning stages) of old-fashioned profilers.
4D's dynamic metrology doesn't depend on air tables or active vibration isolation to obtain measurements of super-smooth optics.

flexcam optical surface profiler, metrology moduleThe FlexCam surface profiler provides high resolution 3D metrology in a highly compact package. FlexCam can be used as an affordable, stand-alone optical surface profiler for in situ measurement of surface roughness or defects on large optics, such as glass windows or films. It easily mounts into a conveyor line to measure surface parameters of passing architectural windows or roll-to-roll flexible films.

4D InSpec Surface Gauge: handheld, high resolution for measuring surface defects on precision machined surfacesThe 4D InSpec Surface Gauge is the world's first handheld, portable instrument for measuring defects and fine features on precision machined surfaces. The revolutionary 4D InSpec accurately measures on curved surfaces, under flanges, thin edges, inside bores and across large surfaces—in just seconds.
