Corona extreme

The ZEISS Spectrometer System for Agriculture

  • Introduction

    Corona extreme and 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.

    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.

    High time for a solution. Corona extreme.

    The quality of natural products is subject to natural fluctuations in the environment. The agriculture industry has to maintain standard requirements for processing materials and related documentation. Corona extreme offers the right technology for accurate process control to maintain consistent quality of the final product. The precise measurements are carried out in real-time to optimize process control and to minimize time, waste and cost. Seamless data integration increases product safety. Applications specific calibration and support can be provided upon request.
