The GS-1160B portable spectroradiometer is a compact and light weight spectrometer suitable for high-speed and accurate spectral measurements of displays. A flicker sensor is also included. The platform's cutting edge technology is superior to filter-based colorimeters and not susceptible to filter matching errors. It delivers true spectral based measurement accuracy required for high color saturation and wide color gamut LCD, OLED, micro LED and quantum dot displays.
LightTough uSpectrum and uFlicker software provide comprehensive color and flicker measurements and analysis.
