About ARCoptix
ARCoptix S.A. is a Swiss company in the field of optical spectroscopy, headquartered in Neuchâtel with production in Tramelan in the Bernese Jura. Founded in 2006 and privately managed, the company specializes in Fourier-Transform Infrared spectroscopy (FT-IR), covering applications in the near-infrared (NIR) and mid-infrared (MIR) spectral ranges. The product range includes desktop instruments such as the FT-NIR and FT-MIR Rocket spectrometers, fiber-coupled FT-IR and VIS-NIR systems, OEM spectrometers (OEM010/OEM011) as well as gas measurement systems, complemented by accessories such as ATR, DR and flow-through measurement modules, light sources (ARClight) and reflection probes. The spectrometers are based on a permanently aligned interferometer with two corner-cube reflectors on a common pendulum arm that rotates on a wear-free flexure bearing. In addition to standard products, the company offers rapid prototyping of custom configurations for specific applications. With hundreds of instruments in use worldwide, ARCoptix has many years of experience in manufacturing and qualifying benchtop and OEM FT-IR spectrometers; one FT-IR system operated outside the ISS for one year (developed at LISA, supported by CNES).
