A spectrally resolved monochromatic light is provided which generally comprises an incoherent small source lamp, a concave grating for spectrally resolving the wavelengths of the light to obtain a particular wavelength, and an optical fiber for collecting and transmitting the particular wavelength. The light source can also have more than one optical fiber output, each having a different monochromatic wavelength. An order sorting device, such as a filter or dichroic mirror can be used to filter out the shorter wavelength radiation resulting from higher grating orders. |
