Corona Process

ZEISS Corona® process

The spectrometer system that meets all necessary requirements at the highest level.

For the highest demands - The requirements in food production environments concerning quality and hygiene are extremely high. The careful use of resources and the avoidance of waste are important factors in terms of the environmental scorecard. To ensure profitable production, process inspections and optimization take on major importance. Corona process allows you to put economic and environmental claims into practice – no matter in which field of the food industry they are operating.

About Corona process

Perfectly coordinated components combined with new ZEISS ProcessAssist systems make Corona process one of the safest spectrometer systems. The quality parameters which are relevant for your process can be measured even more comfortably using the ZEISS ProcessAssist.

Corona process warns you if critical limit values are being exceeded and a reaction is required immediately. The automatic logging of the environmental conditions always ensures reliable measuring results regardless of the sample height, temperature, air humidity or vibrations. If necessary, it also controls internal referencing. To avoid down time, bulb functioning is also monitored automatically. If a bulb fails, the second full-power bulb is deployed immediately and the Corona process can continue its tasks uninterrupted.

Your benefits

Every process is different and has its own very unique conditions – some of which may be extreme. However, for the new Corona process this is not a problem. The large spectral range which covers the visible and the near infrared range enables a broad spectrum of applications.

Corona Process benefits
  • Easy integration into any technological process
  • Compact design: only one installation site is required (optics, spectrometer, measurement head, electronics & referencing are in the same housing together)
  • No need to use light guides: influencing and losses do not occur
  • Stainless steel housing: meeting all hygiene requirements
  • Excellent long-term stability 
  • No frequent external calibration required
  • Measurement accuracy at a distance from 80 up to 600 mm from the sample
  • Unaffected by temperature fluctuations from – 10 to + 50 °C
  • Protection against shock and vibrations: reliability in all process environments
  • 20,000 hours total service life of bulbs
  • Remarkably little maintenance required only
  • Automatic internal referencing depending on environmental conditions
  • Automatic monitoring of bulb function and automatic switching to the second full-power bulb
  • Automatic compensation of sample distance influence even when sample heights vary dramatically
  • Automatic warning when limit values are exceeded

Connected spectroscopy

The future of spectroscopy is in the cloud

Knowledge is power and accessible to all.

Smart, flexible and ready with real-time data - connected spectrometers provide users with near instant insights into production processes and product quality. ZEISS is the first company to offer such an innovative spectroscopy solution. It connects to Microsoft’s Azure Cloud platform, allowing a spectrometer, such as a Corona process, to send its data straight to a central repository. This gives
users unparalleled access to important quality measurements. The information are available to all the individuals responsible for monitoring and optimizing production, speeding up decision making and making processes more efficient and effective.
