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
Valley Design will be exhibiting at the upcoming Optatec Trade Fair in Frankfurt, Germany, along with its German partners Hebo Spezialglas. Optatec is the international trade fair where renowned market leaders and emerging new companies from around the world showcase their innovations in future optical technologies, components, systems and manufacturing processes. Optical technology will continue to play a key role in energy, medical, manufacturing and industrial optics processes, and Optatec provides these developments in a well established, internationally esteemed forum, supplemented by in-depth, expert presentations and symposiums.
