Abstract : The present invention relates, in general, to lens and lens systems, and, in particular, it is an athermal acoustic refractor that may be advantageously combined with an array of electroacoustical energy converter devices for the focusing of acoustical images thereon or therefrom. It is an improved, reversible, temperature and salinity compensated, compound, ultrasonic, electroacoustical transducer lens that is suitable for being incorporated in both active and passive sonar systems, in sonic echo-search-ranging systems, and in any other devices or systems requiring the accurate focusing of acoustical energy under ambient environmental conditions of varying temperature and/or salinity.
