Abstract
Systems and methods for improving night vision systems are presented. Broadband multi-level diffractive lenses are used in place of either or both of the objective and eyepiece of traditional night vision systems. By using one or more broadband multi-level diffractive lenses, the size, weight, and weight distribution may be reduced or modified.
Claims20
A method of reducing at least one of the size or weight of a night vision system, the method comprising replacing at least one first lens with at least one broadband multi-level diffractive lens, the at least one broadband multi-level diffractive lens having optical capability at least equivalent to the at least one first lens.
