MAZeT presents for the first time its software library for spectral analysis and control engineering assignments. With the CBM library MAZeT offers a modular development system, including a software library for spectral analysis and control engineering assignments. The library contains linked routines for sensor steering, interfaces, sensor signal evaluation, algorithms for calibration and spectral calculation, and complete use-specific tools. The library will be delivered by MAZeT, optionally supplemented by the evaluation boards, and can be directly integrated into the customer's own test software and the series software. To that end, based on a verified algorithm, the routines will be ported as the core of the software with the sensor and color algorithms for various target systems, according to the chosen hardware. The test system and the series applications are therefore as identical as possible. The advantage for the customer is clear: The customer can concentrate on his application, without spending time on the development and verification of the sensor and color software, and can get his products to market faster. The software library is available for the True Color Sensors and subsequent operations as well as applications boards. It makes enables greater accuracy in spectral analysis. In this way, based on the JENCOLOR standard boards, an average accuracy of Delta u'v' <0.003 for light sources and Delta E <3 for reflecting bodies and materials can be achieved. Calibration guarantees the sensors' synchronization. Because of the stable interference filter, the sensors change neither function nor parameters over their lifetime within a specific temperature range. It is unnecessary to re-calibrate during operation or their lifetime.
