Advanced 3D Non-contact Optical Profiler using Grasshopper3 USB3 Vision Camera

Zeta-20 3D Optical Profiler using Grasshopper3 USB3 Vision camera

 

3D optical profiling provides a combination of imaging, precise measurement and speed which is not possible with contact techniques such as stylus profilers or atomic force microscopes (AFMs). 3D non-contact optical profilers are used for a variety of measurements, including sub-micron to multi-millimeter step heights and nanometer level surface roughness.

 

Non-contact Optical profilers are typically built on advanced optical microscopes, providing the dual advantage of excellent imaging and no contact with the surface being measured. They use a variety of light sources, usually using high-brightness LEDs, to illuminate the sample and sophisticated cameras to capture the images which are then converted into height information using techniques such as confocal microscopy or interferometry.

 

Non-contact Optical profilers are presently being deployed in many high-technology industries where the surface properties of materials need to be analyzed, such as the characterization of advanced semiconductor packaging, high-brightness LEDs, solar panels and microfluidic devices.
