Distributed sensors, data processing on-board, fast, reliable and maintenance free – that’s the idea of embedded spectroscopy.

For decades, spectroscopy for industrial applications was inherently linked to PC technology and Windows operating systems, because nearly all generic sensor hardware and software was designed for PC technology, which is driven from products for consumers.

The work on a generic embedded platform for spectroscopy, which is as powerful as PC-based solutions was obvious but this needed significant development. Even interfaces like USB, which was never designed for reliable industrial applications, became state-of-the-art in industrial environments.

Embedded spectroscopy, with its special demands, became realistic because of the recent developments in data processing capabilities, combined with low power consumption and the availability of data processing components for industrial requirements.
To specify such a product idea with all the restrictions, advantages and disadvantages is challenging work and forces you with aspects you never face on a PC and Windows operating system. Security and reliability becomes a strong focus and leads to specialized operating systems and well selected 3rd party modules.
Furthermore, parametrization an application instead of programming it, is a feature customers are used to if they work with Windows based software packages for spectroscopy. That makes the difference between a generic platform with fast time to market, in comparison to a special instrument software, coded for one application with closed algorithms [Parametrization vs. Programming]. But, it means also to protect the customer IP [system setup and algorithms] and make the system save for unwelcome access, competitors or hacking [Security].
Spectrometer as a Sensor – which is the idea of distributed systems with on-board data processing capabilities, doesn’t need an Man-Machine-Interface or sophisticated user interface. Such a system communicates remotely with tools for monitoring and setup and more important with process management systems via standardized communication interfaces [Process Interface]. That an important specification for the selection of the operating system and 3rd party code libraries.
