- A panoramic lens for full view monitoring was designed with ZEMAX. The system consists of a concave and convex mirror group and a relay lens. The mirror group enable the lens to obtain a large field of view, and the relay lens projects the virtual image formed by the mirror group onto the detector. The effective focal length is 1.58mm,field of view is 180°in vertical direction and 360°in horizontal, The result shows that the maximum f-θ distortion is less than 5% and the modulation transformation function at 60lp/mm is greater than 0.58, which proves that the image quality of the optical system is good. The system has large filed of view and it is simple in structure and small in volume, which meets the requirements of full view monitoring lens systems.
