Prometheus Series
Colorimeter 27 mm wide-angle

0.0001 - 2 800 cd/m² (20 000 cd/m² in UHL mode)

When speed is paramount, the Prometheus 27 mm wide-angle collimating lens colorimeter is the one to watch. It’s color measurement speed goes down to 22 ms or higher, depending on luminance level and frame frequency. It makes this Prometheus the fastest colorimeter in the world and a perfect choice for the measurement of any type of display, combining incredible speed with near perfect XYZ filter characteristics and low luminance performance. Highest accuracy, even at high measurement speeds.

“The fastest colorimeter in the world”

Perfect filters

The Prometheus Series offers further improved in-house made filters which are near-perfect to the CIE 1931 or CIE 170-2:2015 color matching functions. This results in highest accuracy, even for display measurements where the spectral power distribution in a production batch might vary.

Fastest colorimeter

The 27 mm Prometheus is the fastest colorimeter for display measurements in the world. But nonetheless the accuracy is top-notch. You can't ask for more.

Flicker and waveform

With the high sampling speed of the Prometheus colorimeter you get an all-in-one solution to measure flicker, adjust V-Com or assess the waveform of the display signal.
