Abstract

With the present trends toward miniaturization, the demand for complex optical elements with surface features is increasing. If these complex optical elements, such as Fresnel and diffractive optics, are fabricated in glass they should be superior to plastic, both in optical quality and environmental stability. To demonstrate the replication of diffractive and Fresnel optics, Fresnel lenses were prepared by a sol-gel molding technique. The optical quality and performance and dimensional characteristics of the lenses are reported. Optical and physical properties tested included glass homogeneity, UV/VIS/NIR transmission, light scattering and surface profilometry. Optical performance testing indicated that these glass Fresnel lenses are as good as their parent plastic Fresnel lenses from which they are molded.
