GS-1160 Display Measurement System

LightTouch uSpectrum Software

  • Compact, high speed, and lightweight spectrometer/flicker meter for accurate and repeatable display measurements.
  • Available in either a portable battery-powered or industrial/desktop version.
  • Suitable for color and intensity measurement of all display types including LCD, LED, OLED, and Quantum Dot.
  • Spectroradiometer instrument with superior accuracy and repeatability relative to Filter Type color analyzer. Avoids measurement errors of Filter type analyzers which can be inaccurate if exacting coating tolerances are not met.
  • Supported by Gamma Scientific’s flexible LightTouch uSpectrum and uFlicker software for color and flicker analysis.
  • Backed by ISO 17025 Certified and NIST-traceable calibration.

LightTouch uFlicker Software

GS-1160

  • Portable and battery-powered version that can be used as a portable display test or calibration system or as a desktop display measurement system.
  • Easy to use with integrated touchscreen display operation. Simply position the optical sensor near the display and a press of a button displays the measurement on a 3.5″ color display.

GS-1160B

  • Industrial/desktop version operated with Gamma Scientific’s LightTouch uSpectrum and LightTouch uFlicker software
  • Compact and lightweight design for ease of placement in production and laboratory settings. Can be easily implemented throughout the display manufacturing process to test display quality.

Spectral Sensing Technology

  • Delivers key display measurement capabilities for Color Chromaticity, Gamma, White Balance Adjustment, Contrast, Flicker (VESA & JEITA), and uniformity.
  • Luminance measurement range: 0.05 to 5,000 cd/m2
  • Color measurement in Chromaticity, x/y/u’/v’, XYZ, x10, y10, u10, v10
  • Wide range of Flicker Measurement, JEITA, VESA, CONTRAST (Max/Min), RMS, Time Domain, FFT
  • Full Spectral data and spectrum graphics
  • Fast mode measurement, 100us to 5000ms for productivity demands
  • Automatic dark calibration
