• 14 - 17 October 2019
  • Rochester Riverside Convention Center | Rochester, New York, United States
  • See us in Rochester New York, at the INTEROPTICS Booth 416
  • Many features
    (in a low cost system!)

    • Easy to use, 4 inch aperture downward looking, rigid platform
    • High throughput, vibration isolation table not required
    • High resolution, low distortion 1x and 4x optical zoom
    • Low coherence, no spurious backside fringes
    • High reliability LED light source at 633nm
    • Turn-key system with integrated staging
    • Sub-nanometer precision

    Stop using laser Fizeau interferometers for flat work!

    Add capacity for flat testing with lower cost OptoFlat.
    Free up other laser interferometers for spherical work.

    Measure flatness

    Of thin glass without backside fringes

    Measure wavefront

    With optional reflection flat fixture

    Measure process fingerprint

    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.

    Presenting OptoFlat

    InterOptics introduces OptoFlat, flatness interferometer incorporating engineered coherence for high precision and capability to measure plane parallel optical components without spurious interference from the backside.


    InterOptics Building

    InterOptics operates from the Shamrock Optics Center, an 18,000 square foot facility with temperature controlled metrology rooms supporting optical fabrication and precision CNC machining. Assembly areas include HEPA clean airflow benches.

    We are growing, looking for more people to join us in creating new precision optical metrology systems.
