This paper describes a wide angle fovea (WAF) telescope developed to help rangers save the people floating on the sea in the aftermath of tsunamis and other disasters. The WAF telescope is designed using a proposed Multiple-Stage WAF model having both a wide field of view (FOV) so that it never misses a moving target once it is captured and a high magnification in the central FOV that can resolve detail. This design concept is inspired by the smart function of the eyes of humans and raptors. In other words, the authors design an optical telescope with the dual functions of both wide angle surveillance and resolution of detail in order to improve its usability and convenience. The specification of the prototype has been determined paying attention to this point. The produced prototype has a handy size because it uses two aspherical surfaces in the entire lens compound system. We have tested the prototype and discussed its performance.
