The Aris spectrometer is 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 sensitivity than other spectrometers in this price range. An optimized stray light suppression provides larger absorbance values. It is available in six standard wavelength ranges that can be customized using a large choice of available diffraction gratings.
