ZEISS Corona® extreme

The robust spectrometer system for agriculture

Successful agriculture production has always been a question of experience and commitment. Wrong decisions can have serious consequences. In today’s ever changing environment, nature cannot be fully planned and accurate results cannot always be determined. However, through targeted examination of the process, it can be analyzed better. With over twenty years of experience in process technology, ZEISS is one of the world leader in the measurement and analysis of continous process applications.

Precision decides. Every day, in real-time.

ZEISS Corona extreme and ZEISS InProcess software is the spectrometer system designed to increase productivity in agriculture analysis. The idea was to create a measuring sensor, which is a key component of the process in extreme conditions for the entire product life cycle. With the ZEISS competence in hardware, software and engineering this resilient and precise system can withstand extreme workloads and is considerably superior to lab measurements.

ZEISS Corona extreme is designed based on much application-related experience and provides reliable measurement results for each sample. The compact system is easy to install and can be operated independently using the embedded controller, which enables a direct evaluation and output of the predicted data without the use of a computer. The spectrometer features fibre free, high-energy illumination with outstanding optical properties and internal referencing.
