Caption

When two lenses with similar surface curvatures are joined together, the light rays that reflect from the two surfaces have slightly different path lengths and interfere with themselves. The path length difference increases the further away from the center of the lenses the light reflects, thus generating constructive interference for the different colors contained in white light.
