Avenir Compact Spectrometers

The Aris spectrometer is the next step into the future of embedded spectroscopy. A laboratory-grade instrument that also meets the size, price and reliability requirements for portable and industrial applications. With its high-throughput optical design, the Aris delivers 2 to 4 times better sensitviity than other spectrometers in this price range. An optimized stray light suppression enables the measurement of larger absorbance values.

The Aris offers an unsurpassed flexibility to adapt the spectrometer to the requirements of a specific application. It is available in six standard wavelength ranges that can be customized using a large choice of available diffraction gratings. The default entrance slit of 20 μm is user-replaceable and can be easily exchanged to obtain better sensitivity. Standard configurations include one of two image sensors (see below) with more choices available on request. The powerful microcontroller performs on-board auto exposure, averaging, buffering and spectrum processing. In addition, it enables the implementation of application-specific spectrum evaluation. With its proven reliability in rough conditions and compact size, the Aris bridges the gap between laboratory and field spectrometers.
