The GS-1164-6 spectroradiometer provides six view-angles of display measurement with one click. Displays can be tested simultaneously from the six different view-angles to provide characterization and immediate insight into how they will be viewed in the real-world.

As part of the Vector line of Display View Angle Color Testers, this is the only available six-angle spectroradiometer system providing one-click, simultaneous six-angle display testing.

The cutting edge technology empowers laboratories and production companies to perceive what their customers will see from the different viewing angles for all their display-driven technologies. This enables laboratories and production to create better quality products, streamline their processes, and decrease their costs.

1 Click, 6-Simultaneous View Angle for Rapid, Accurate and Repeatable Display Characterization


• Simultaneous luminance and color measurements at six different angles
• Rapid and accurate simultaneous measurements optimize the testing process with repeatable results
• Measure the true spectral content of color at six view angles
• Especially well-suited for high color saturation or wide color gamut OLED, micro-LED, and quantum dot displays
• Integrated flicker sensor: 100K samples/second
• Luminance, CCT, CIE x, y, u’, v’ and spectrum
• Contrast, white balance and color gamut determination
• Auto darkness correction
• USB 2.0 and RS232 SCPI command compliant and SDK/API library support

*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
*6    Input source must be a stable light source
