Corona® process The spectrometer that does it all

Corona® process from ZEISS is the one spectrometer system you need for all your measurement needs. With its extended wavelength range, it can determine ingredients and colors simultaneously and provides precise and reproducible results.

  • Results in seconds
  • Real-time monitoring
  • Conveyor belt measurement
  • Optimal process control
  • Increase efficiency

Get the full picture Measure color, ingredients and more

A full-scale spectrometer, such as Corona® process from ZEISS captures all the crucial quality information in the 380 to 1650 nm wavelength range. This means that you can measure true color values as well as ingredients at the same time, without additional filters or changing the device.  Corona® process provides you with precise, reproducible results to optimize your production, reduce waste and increase profit.

Optimizes your production Use resources better, react to process variations, adjust in real time

From a variety of agricultural applications to food production, Corona® process provides you spectroscopic measurement in real time, all the time. Determine the quality of ingredients instantly and make crucial decisions or change the product you’re producing without interruption. Determine the quality of raw materials and use them in a targeted way, increasing the efficiency of production.

Consistent performance Accurate data regardless of distance

Corona® process can be mounted on conveyor belts and downpipes, providing measurement without direct contact with the sample. This gives you all the data you need with the same performance at a distance of 100 to 600 mm. Internal referencing provides even more accuracy and mitigates changing environmental conditions. Intuitive software and easy integration into existing networks completes the package.

The ZEISS Corona® process does not only help us to take immediate action on near real time quality exceptions, it also helps us provide targeted training and feedback to our teams.
