Abstract

A hybrid diffractive/refractive visible lens with small F-number of 1.5 is proposed based on the special chromatic aberration of diffractive optical element. It is used in the optical system of visible camera for space debris. The visible lens has an effective focal length of 100 mm, a working wavelength range of 0.5-0.8μm and a field of view 6°. Firstly, the lens system consists of three groups and five lenses. Then, aspheric and diffractive surfaces are used in order to correct high-order aberrations resulting from large relative aperture. Finally, the lens is designed with the help of Code-v optical design software. The lens is evaluated by energy concentration, the dispersion spot diameter, lateral color, distortion, the simulated final design shows adequate image quality. The method puts forward a new ideas for visible camera for space debris optical system design and had an important reference significance and application value.
