High-pass filtered maps show polishing marks
OptoFlat, designed for production quality control and
incoming quality assurance of polished plano optical components is a low cost,
high performance flatness interferometer. Quickly and efficiently measure surface flatness of mirrors, coated and uncoated,
beamsplitters, windows, prisms, thin glass wafers and glass hard drive substrates in a
small footprint, rigid platform that does not need a vibration isolation table in typical
lab and production enviroments. Measure the flatness of precision polished metal and ceramic components as well.
