Abstract :
In resent years, with the improvement of optical process and the increase of new optical materials, many kinds of zoom systems have appeared and the same good imaging quality as the fixed-focus systems. As a result, they have been widely applied to many fields. In this thesis a negative compensation zoom system was designed. The optical design finally reaches the technical requirements. When the wave length is from 0.4358 to 0.6562μm, the focal length is from 30mm to 600mm and the variable time ratio is 20, the relative aperture is 1:5, the system length is less than 450mm. A small pressure angle, steady and smooth cam curve was designed by a new optimum method of zoom cam curve, which realized the design of miniature zoom system.
