ABSTRACT:
Selector for separating at least two wavelength bands from a complex light introduced into the apparatus through the end of an optical fiber (12) arranged in the immediate vicinity of the focal point of a concave mirror (5) producing a parallel beam directed towards a plane reflecting device, the return beam being focused towards an output optical fiber. It comprises at least one plane multidielectric layer (8) interposed between the concave mirror (5) and the plane reflecting device (10) and forming, with the vertex axis (6) of the concave mirror, an angle which is slightly different from that of the plane reflecting device, each multidielectric layer having a discontinuity in the vicinity of the vertex axis of the concave mirror.
