As an example, for a lens 1 meter away, the facets will be unresolvab-le for a pitch size of 0.29 mm or smaller. WebIn almost all instances, Fresnel lenses are plano-convex. This fact, along with their aspheric profiles and their low – numbers, leads to strongly asymmetric behavior. Figure 7 shows a typical Fresnel lens – one correct for the case of grooves toward a collimated beam, plano side toward the focus. (This type of Fresnel lens is referred to ...
