New Method for All Movable Zoom Lens Design
In order to get the simple computational formula for all movable zoom lens and reduce excessive dependence on designing experience of zoom lens, a new way to calculate optical-power distribution of zoom system is proposed. Taking the group spacing as initial parameter and the actions of components as independent variables, the corresponding optical-power distribution and actions of components which satisfy the constraint of group space is get. This method reduces the difficulty of optical-power distribution and it is more important it provides us with another way to find the new varifocal moving mode. After getting the power distribution, we also deduce a simple way to obtain actions of each component. In order to prove the feasibility of this method, a four movable component zoom lens is demonstrated and the calculation result agrees well with the optimized result.
