Lexitek's patented method of fabricating Near-Index-Match™ optics is a new approach to making affordable novel optics in small quantities: aspherical, diffractive, and hybrid refractive-diffractive optical elements.  Examples include beam-shaping optics (e.g. Gaussian to flat-top), corrector plates, fast plastic collectors, achromatic hybrid refractive-diffractive elements, and pseudo-random phase plates, among others.
