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