Fresnel Lenses Brochure. FM6 Fresnel’s original lens was used in a lighthouse on the river Gironde; the main innovation embodied in Fresnel’s design was that the center of curvature of each ring receded along the axis according to its distance from the center, so as practically to eliminate spherical aberration
Optical Tooling - Fresnel Tech We offer small-volume production of directly machined optics in a variety of diamond-machinable substrates, such as IR and visible transmitting crystals, non-ferrous metals, and polymeric materials
Resources for Optical Design - Fresnel Tech Use our spec sheets, brochures, and optics resources to help you determine the optical lens and optical material best suited for your application
