The Sonic Spectrometer C-700-U is designed for motion and still Image capturers who must produce quality results with proper subject color while working with multiple types and brands of light sources. A full-spectrum color meter, the C-700-U can precisely measure LED, HMI, and Fluorescent as well as tungsten, natural light and electronic flash. The C-700-Us' large color touch screen displays light-source color spectrum and CRI for multiple sources plus Kelvin (correlated color temperature), Illuminance (foot-candle or Lux) and light source filtration values in Mired, CC as well as filter correction values for major light source and lens filter brands. Its high-resolution measuring system, featuring CMOS sensor, enables capturing spikes in light source output to provide unsurpassed color measurement accuracy. Different than any spectrometer today, the C-700-U meters not only displays more light-source information, it also provides filtration information to correct and modify light color for cleaner recording and simpler post process.
