Model : Cronus-CC

Description :

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.

• Spectral range 380-780nm
• Spectral output or colour values output are both possible
• Measures xy, CRI, lumen, spectrum, flicker
• High speed flicker measurements: 186.567 samples/second
• Auto-range function
• Excellent linearity
• Dark current compensated
• USBTMC compliant, SCPI command set, high speed device
• Numerous interfaces, ideal for system integration
• Internal calculations for most common parameters, saving processing power in production environments
