Abstract

We present a recently developed miniature scanning Fourier-Transform spectrometer (ARCspectro ANIR), which is based on a lamellar grating interferometer and uses a micro-mechanical actuator. The small dimensions of the interferometer (35 mm x 35 mm x 65 mm) and its low weight makes this device a truly portable Fourier-Transform spectrometer. Two different versions of this new spectrometer are presented: one version uses an InGaAs photodiode (0.9μm to 2.6 μm) and the other a MCT detector (2 to 4.5 μm). Their performances are discussed and also illustrated with measurement and application examples.
