Abstract

A wavelength spectroscopy device includes, on a substrate, a filter cell CF constituted by two mirrors separated by a spacer membrane, the filter cell being made up of a plurality of interference filters. Furthermore, the device also includes an emission cell CE having a plurality of emission sources, each of the sources being associated with one of the interference filters.
