Abstract: A prism including a substrate faceted to provide a plurality of flat surfaces, wherein at least two of the plurality of surfaces, each including a filter coating, form at least two filter surfaces, wherein each filter surface selectively permits passage of a predetermined wavelength and reflects remaining wavelengths along an optical path towards another of the plurality of surfaces, optionally another filter surface, wherein an angle of incidence of each of the plurality of surfaces along the optical path is equal or nearly equal. An apparatus incorporating the prism and its use for splitting a light spectrum into a plurality of wavelengths or wavelength ranges.
