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 lighting 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.

Application areas
The Cronus is used for measurements in solid state lighting development and production processes. Due to the spectrometer the Cronus is ideal to develop and monitor the spectral colour of LED light sources during development, during long term testing or in production.
The colorimeter in the Cronus allows for high-speed sampling in your production line checking the quality of all your products, leading to increased product quality and production efficiency. The spectrometer can be used for both spectral and colour measurements.
Controlling your LED lighting system is crucial. Not only visible light flicker within the range ~3 to ~70Hz but also invisible (non-perceivable) flicker can have an effect on human health. Ranging from headaches, migraines or impaired visual performance to an increased risk of seizures research has shown that flicker is an effect with reason for concern.
The build-in colorimeter and large internal memory of the Cronus allows for high speed measurements over a long period of time. This enables the user to check flicker effects over time and during fade of the light source. Adjusting the driver during development and checking the flicker effect of each light source during production leads to increased performance and end-user satisfaction and health.
Optical configurations
The Cronus spectro-colorimeter is available in two optical configurations: with fixed optical configuration and fibre optical configuration. All Cronus’ products are produced and calibrated to your order and delivered with the accessories needed to start your measurements. Neutral density filters can be applied to the system to change the measurement range.
The Cronus with fixed optical configuration is built with the optics directly attached to the body creating a robust and compact measurement system. For lighting applications, a 1cm² Cosine Corrector is available as fixed optics solution.
The Cronus with fibre optical system comes with a M8 fiber connector, an optical fibre and an optical system or integrating sphere. M8 Fibre connector: the Admesy fixed position fibre connector has been developed to connect the optical fibre in a fixed and uniform way from calibration to final use. Due to this fixed position measurement results are more stable. To the fibre optics connector, fibers and accessories such as separate cosine correctors or integrating spheres can be connected. For the latter light source measurements Admesy offers a range of integrating spheres.
For integration with SMA based measurement systems (e.g. integrating sphere), a SMA connector is available.
