Fresnel Technologies

Fresnel Technologies Inc. is a precision optical tooling and manufacturing company specializing in diamond machining capabilities for the production of molds, prototype optics, and finished optical components across multiple materials and geometries. The company operates an extensive suite of ultraprecision machining equipment, including two two-ax... is ultraprecision lathes and a four-axis ultraprecision freeform surface generating machine, all equipped with on-machine measuring and compensation devices that enable tight tolerances and minimal rework. Fresnel's diamond machining portfolio supports workpiece diameters up to approximately 24 inches (600mm), or nearly 28 inches (710mm) with specialized fixturing, and the company manufactures directly machined plastic optics in small to mid-volume production runs as well as diamond-machined components from materials including germanium and electroless nickel. The company's technical capabilities span non-rotationally symmetric surfaces such as phase plates and anamorphic lensesenabled by fast tool servo technologyalongside conventional aspheric arrays, large linear structures, and parqueted lens arrays, complemented by a dedicated Fresnel lens generating machine. Fresnel Technologies has demonstrated exceptional precision performance, achieving surface finishes as fine as 2 nanometers Ra and form errors of 44 nanometers peak-to-valley over 50mm workpiece diameters without relying on on-machine error compensation, establishing the company as a leader in ultraprecision optical manufacturing. The company serves customers requiring complex mold inserts and optical components for applications demanding extreme accuracy and surface quality. Fresnel Technologies' technical leadership is reinforced by the recent addition of two world-recognized experts in ultraprecision machining to its technical staff, positioning the company to deliver advanced solutions for both conventional and unusual optical geometries, including lenticular arrays and specialized linear-symmetry ...Read More
