SS420

The SS420 Goniometer provides a wide range of testing capabilities. Its unique design integrates collimated optics with a diffraction grating spectrometer and a goniometer which allows for off angle measurements of luminance, chromaticity, contrast, etc. versus viewing angle. The system keeps the lens very close to the display which greatly reduces measurement errors such as veiling glare. This design also greatly reduces the space require for testing.

With the ISO-3 option, the SS420 can perform all of the ISO9241-305 Unwanted Reflections measurements. This option includes three light sources, a reflectance standard and other hardware to to perform this rigorous test standard.

The SS420 can be used on a stationary stand for fast single point measurements or use one of our positioners for automatic measurements at any location on the display under test.

Applications:

  • Flat Panel Displays – OLED, LCD, CRT, Plasma
  • Measure Luminance/Contrast vs. Viewing Angle
  • Automatically test up to 93″ Diagonal Displays with SS90 Positioner
  • Perform ISO9241-3xx Reflectance Measurements with ISO option
  • MV Remote software to display test patterns on all type of displays, laptops and Android devices
