A diffractive optical element (DOE) uses thin micro‐structure patterns to alter the phase of the light that is propagated through it. Those micro‐structures, once properly designed, can manipulate the light to almost any desired intensity profile or shape. This technology enables many functions and light manipulations which are not feasible with standard refractive optics.

A diffractive optical element (DOE) uses thin micro‐structure patterns to alter the phase of the light that is propagated through it. Those micro‐structures, once properly designed, can manipulate the light to almost any desired intensity profile or shape. This technology enables many functions and light manipulations which are not feasible with standard refractive optics. In many applications, these functions are highly beneficial and improve system performance significantly. Diffractive optical solutions have many advantages such as: high efficiency, high precision, small dimensions, low weight, and, most importantly, are flexible solutions that meet a variety of different applications' requirements.
