ABSTRACT:
A system and method for separating a component signal having a predetermined wavelength from a signal carried over a range of wavelengths is disclosed. The system comprises a first filter for transmitting light of the predetermined wavelength. The component signal is reflected rather than transmitted. The system further comprises a second filter for transmitting light of a second predetermined wavelength. The second filter is in the transmission direction from the first filter. Thus, the component signal is separated by transmission by the first filter and reflection from the second filter.
