ABSTRACT:
The invention relates to tunable wavelength-selective optical filters for letting light of a narrow optical spectrum band, centered around an adjustable wavelength, to pass through and to stop wavelengths lying outside this band. More particularly, the invention relates to a process for the collective fabrication of optical filtering components, consisting in producing a plurality of optical filtering components on a transparent substrate. The process further comprises covering the plurality of components with a transparent collective cover, in optically testing each component individually, and in separating the various components from one another. The invention also relates to a wafer of components, comprising a transparent substrate on which a plurality of optical filtering components has been produced, a transparent cover (8) collectively covering the components. The wafer further includes means for individually testing each component.
