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.

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.
