WAFER FLATNESS MEASUREMENTS
 

Patent pending non-contact Optical Interferometer for measuring flatness of thin, transparent wafers, windows and substrates by interferometric comparison to an optical reference flat. Unlike with Fizeau Interferometer, the need for an application of film on the backside of thin transparent wafers has been eliminated.

See the schematic and photo of the Indars flatness measurement interferometer.



TRADE SHOWS
 

Please join us at the upcoming Optatech International Trade Fair for future optical technologies, components, systems and manufacturing being held in Frankfurt, Germany June 17-20, 2008.
