A light dispersion filter comprising at least three light transmitting layers each having an identical product of refractive index and thickness, and a plurality of partial reflection layers disposed alternately with the light transmitting layers and each having a specified reflectance. Alternatively, the filter comprises a plurality of etalon resonators that are disposed in series so that a product of the reflectance of air and the interval between etalon resonators is equal to a product of the refractive index and thickness of the light transmitting layer. |
