High Speed 3-D Surface Inpection Tool from Nikon

Nikon Instruments, Inc., a world leader in the development and manufacture of optical and digital imaging technology for biomedical and industrial applications, introduced the BW-H501 high-speed 3D surface profile system, offering rapid high-precision 3D surface inspection. The BW-H501 system features real-time height observation with high-precision height measurement, making analysis and evaluation of object surface roughness possible. Additionally, a heated stage allows observation and analysis of the deformation process of film and gel samples in real time.

"Observation and analysis of optically diffusive surfaces is a weakness of conventional optical systems, but it presents little difficulty for the BW-H501," said Mike Metzger, General Manager, Industrial Microscopy & Metrology. "The BW-H501's unique combination of a high-speed camera system with newly developed fringe cycle method software makes surface profiling possible in as little as 200ms for a height of 40 micrometers."

Using the fringe cycle method, the coordinate value on the Z-axis with the maximum local focus measure is taken as the height of each pixel, generating an interference fringe on the surface of the object with a two beam interference objective lens. This allows the BW-H501 to achieve effective height resolution of 100 nm and repeatable precision of Sigma =3D 10 nm. Additionally, the BW-H501's X-Cycle Imager makes image capture of 900 fps possible with output and display of real-time height images at 5 fps. Equipped with Nikon's BridgeElements software, multiple images can be processed simultaneously, allowing real-time image comparison.
