Paper Abstract

Two-component zoom systems are a basic part of all zoom systems. The first zoom systems appeared at the end of the 19th century in Germany. Dunouer has shown the possibility of creating two-component zoom converters with a definite magnification range and the appropriate correlation between the optical powers of the components. After Dunouer several types of the two-component zoom objective lenses have been designed. Typically, they had small magnification range (less than 2X) and were more complex than was necessary. In the 1970s designers began to pay more attention to the creation of two-component zoom projection systems. Most recently, special telecinema zoom projection systems have been created. An optical telecinema system consists of a zoom projection system and a prism splitter to split the beam into three color channels. Its purpose is to project 8, 16, and 35 mm movies in a television. Such a zoom system is supposed to have telecentric chief rays in image space and a long distance from the last surface to the image. The creation of new zoom systems has to be founded on the general theory of first- and third-order design to find the optimum parameters of the system.
