PROBLEM TO BE SOLVED: To provide an optical system with an aperture stop that transmits light through apertures having different diameters based on the wavelength of the light. SOLUTION: The imaging system includes a wavelength dependent aperture stop, which transmits light with different ranges of wavelengths through apertures of different diameters. Thus, different colored light has different F-stops, which can be selected based on the power transfer and image quality requirements for the different colored light. For example, a smaller F-stop may be used with a weaker light source to produce a higher throughput for a specific range of wavelengths. Accordingly, the optical system's design and optimization are dependent on the wavelength and the F-stop. COPYRIGHT: (C)2007,JPO&INPIT
