A hybrid diffractive-refractive binary optical system has been successfully designed and fabricated in Changchun Institute of Optics and Fine Mechanics
Academia Sinica by the authors of this paper.The focal length of the system is 800 mm
the effective aperture 76 mm and the imaging spectrum range from 435.8 nm to 656.3 nm.The measured axial MTF value of the system is 0.75 at the frequency 20 lp/mm
which offers significant improvement over that of a conventional system finely designed at the comparable conditions.
