Abstract

Many of observation optical systems consist of two parts: main observation objective with long focal length and narrow angular field and wide angular viewfinder lens. We propose to combine the two mentioned optical systems in one varifocal objective. In this case refractive system of viewfinder is integrated into the scheme of the catadioptric objective. Changing of magnification is implemented by “replacing” certain optical-mechanical components either in main or in viewfinder objective. In this paper it is described optical design of proposed approach and its technical realization.
