spectrometer & colorimeter
Cronus: the first spectro- and colorimeter in one
The Cronus is world’s first spectro-colorimeter combining a high end VIS spectrometer with a high speed XYZ colorimeter. This allows the user to vary between the high-speed colour and flicker measurements of the colorimeter and the high accuracy and detailed colour information of the spectrometer.
The Cronus is tailored for display applications where the combination of speed and accuracy is needed in for example flicker measurements. The Cronus is available in a fixed optics and fibre optics version. Just as other Admesy products it is developed with an industrial use in mind combining ease of use, minimal calibration needs, high-speed measurement capabilities with a compact and robust design. The Cronus offers laboratory results with a workforce attitude.

1 Speed and repeatability are directly related to each other, a lower repeatability can increase speed and vice versa.
2 Data is without the auto-range function, auto-range will add additional time.
3 Measurements are performed on a LED backlight LCD screen.
