Innovative flooded mask for a well-corrected vision both under water and above water

Abstract

This paper describes the development of an innovative scuba mask, which can be flooded by water and is able to provide a correct sight both underwater and in air, thus overcoming the drawbacks of traditional diving masks. The working principle of this new flooded device corresponds to the underwater telescope. Optical design analyses have demonstrated that it is able to provide a well corrected vision in both underwater and above-water conditions. The development of the optical configuration for the mask is illustrated presenting various stages of the optical project. The device has been optically and mechanically designed and then realized. Beyond the optical requirements, the optical design takes into account compactness, low fragility, diver comfort and other practical aspects in view of a possible mass production.
