Abstract: Two photoelectric detector elements, having substantially different response wavelengths, are mounted in a housing in cascade relationship. The outer element is selected to be transparent to the response wavelength of the inner element and it is provided with an integral filter that is transmissive at the response wavelength of the inner element. Anti-reflective coatings are used to minimize reflective losses.
