GS-1163 Multi-View Angle Spectroradiometer

The GS-1163 multi-view angle display spectrometer is designed to measure color and luminance at three different angles simultaneously. As part of the Vector line of multi-view angle display spectrometers, the system integrates a flicker sensor and three spectrometers into one module at -60, 0, and 60 degrees for high-speed and accurate concurrent spectral measurements. Its innovative technology is superior to filter-based colorimeters and not susceptible to filter matching errors.

The system delivers true spectral based measurement accuracy that is required for high color saturation and wide color gamut OLED, micro LED and quantum dot displays. LightTouch uSpectrum and uFlicker software provide comprehensive color and flicker measurements and analysis.

*1    Luminance and color testing are based on standard light source at 2856K, 6500K and 9300K.
*2    Measure in normal mode with temperature 23±2 °C and relative humidity 50% or less
*3    Repeatability test is based on the status of shutter opening
*4    Input the 550nm monochromatic light and measure the stray light ratio at 550nm ± 40nm
*5    Testing condition: Sync mode at 60Hz. Sample speed depends on the measured sample. If the sample uses PWM, it will take longer
