K. Takanami and S. Komatsu: Dual Wavelength Binary Lens Using Dispersion Characteristics, Extended Abstracts (Optics Japan 2001) , The Optical Society of Japan, 255-256 (2001)

The Diffractive Optical Element (DOE) plays a major role in various applications such as optical interconnection, optical signal processing, etc. It causes chromatic aberration when the DOE is illuminated with the light whose wavelength differs from the design wavelength. We propose a dual wavelength binary lens (DWBL) composed of two DOEs which have different dispersion characteristics. To decrease the sampling error, the profile of the binary lenses was optimized by using simulated annealing.
