This paper describes a wide angle fovea (WAF) telescope developed for supporting rangers to help the people floating on the sea because of serious Tsunami disaster. The WAF telescope is designed using a proposed Multiple-Stage WAF model which has a wide field of view (FOV) not to miss a moving target captured inside once and a high magnification in the central FOV to observe in detail, simultaneously. This design concept has been inspired from a smart function of the actual human eye. In other words, the authors have given an optical telescope multiple functions of both wide-angle surveillance and detailed observation in order to improve its availability. Specification of the prototype has been determined paying attention to this point of view. The produced prototype has achieved a handy size by using two aspherical surfaces in the whole lens compound system.
