The invention relates to wavelength-selective optical filters for allowing light of a narrow optical spectral band, centered around a wavelength (lambda<SUB>c</SUB>) to pass through them, while reflecting the wavelengths lying outside this band. According to the invention, the transfer function (T<SUB>1,2</SUB>(lambda)) of the component is defined by multiplying two transfer functions of spectrally offset Fabry-Perot filters.
