Whether you need one piece, a few hundred, or millions, Fresnel Technologies can take your preliminary design through prototyping and testing to production. We offer single point diamond turning and machining, CNC machining, injection and compression mold manufacturing, and tooling for specialized optical surface finishes.
Our diamond machining is ideal for the production of prototype optics and the manufacture of high-quality optical molds. 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.
Our state-of-the-art diamond-turning machines include dual-axis ultraprecision lathes and two four-axis ultraprecision freeform surface generating machines, all fitted with on-machine measuring and compensation devices. Diameters of nearly 28" (710 mm) can be turned.
Fresnel Technologies has extensive experience designing and building molds for lenses and arrays of lenses, from single cavity to high-volume multicavity molds. We have developed many specialized techniques, unique to our company, to permit the molding of high-precision, highly reproducible molded optics. We are very skilled and experienced in the production of molds for flat and curved parqueted arrays of lenses. Fresnel Technologies has the expertise necessary to produce molded optics with submicron features.
Our facility is also home to a world-class all-CNC machine shop. Our advanced machines are capable of micron-level accuracy. The primary focus of this facility is the building of injection and compression molds for our own and our customers' products. We offer high-precision lathe turning; high-precision 3- and 5-axis milling; and form, wire, and small-hole EDM.
FTI has a comprehensive in-house metrology lab, staffed by skilled scientists and technicians. This enables the assessment of quality and verification of compliance with customer specifications throughout the production of prototypes, molds, and molded optics.
Another area of FTI's tooling expertise is the texturing of mold surfaces to produce a variety of desired optical effects, including gaussian distribution diffusers. These methods are commonly used in illumination optics and passive infrared lens arrays.
Our machining facility enables us to produce prototypes and molds for unusual items, including those lacking rotational symmetry. Examples of optics that we’ve made include:
Our team’s expertise in the field of ultraprecision machining and other optical specialties make our facilities ideal for production of your optical components.
