• One Second, One Spectrum, No Kidding

    FlashQE Uses a Revolutionary Solid State Lightsource
    • All wavelengths measured simultaneously

    • Solid state lightsource >10,000 hr lifetime

    • Extensive, built-in feedback control for excellent stability

    A New Kind of Lightsource
  • QEtech_noise

    Diagram showing the results of a nine-hour gauge study, where 32,000 QE spectra were acquired at a measurement rate of one per second. First and last EQE spectra are shown, as are the 6-sigma error bars that were calculated from the entire data set.

    Superior Stability and Repeatability
