Design of Zoom Lens System with Movable Components Including Large Aperture and with Ultra-Wide Field of View
A design method is proposed for achieving ultra-wide field of view and high-resolution imaging in an optical system including a zoom lens with a large aperture. By analyzing the principle of the optical system and comparing the mode of zoom compensation, an all-motion mode of compensation is adopted to enable zoom motion in the entire system. The primary aberration theory and the ZEMAX software program are applied to determine the initial structure parameters. The optimized design includes 14 components for the refraction lens aperture and large field of view zoom system. The parameters include a system working band of 400?700 nm, focal length range of 6.54?17.00 mm, changing time ratio of 2.6, full field of view angle ranges of 60°?178°, and F-number of 2.8. The modulation transfer function value in the Nyquist frequency, at 55.6 lp/mm, is greater than 0.40; therefore, the imaging quality of the proposed system very good and meets the design requirements.
