Virtual reality and augmented reality devices require increasingly demanding optical components. Head mounted displays for VR systems often use molded Fresnel lenses, which can be affordably mass produced, maintain low weight, and still achieve high

An important, but largely invisible, area of polymer optics involves sensing the motion of warm objects. It can be further subdivided into optics for security, for energy conservation, and for convenience; the area has become known as optics for the

Electro-Chemical Polishing is routinely used in the anodizing industry to achieve specular surface finishes of various metals products prior to anodizing. Electro-Chemical polishing functions by leveling the microscopic peaks and valleys of the subst

Advances in freeform optics, particularly fabrication, allow for the creation of new lenses. Four freeforms are described and fabricated: an atoric lens; a Zernike surface; an elliptical, anamorphic Fresnel lens; and a sinusoidal spiral surface.

We have investigated the light collection and collimation properties of both Fresnel lenses and the nonimaging (TIR) “cones” typically used with LEDs. We have measured the integrated light output and its spatial distribution, and we have also mea
