Fresnel Technologies, Inc. (FTI), founded in 1986, is a world leader in polymer optics. Although our roots are in Fresnel lenses, we specialize in a variety of polymer optics, including continuous-surface aspheric lenses, lens arrays, diffusers, and freeform optics.
From concept to production, we do it all under one roof: optical design, tooling, custom metrology, manufacturing, and assembly. FTI can quickly fabricate individual optics for prototyping and create single-cavity molds for low-volume production, then manufacture pristine multicavity molds for high-volume orders. With our two-axis and freeform-generator diamond-turning machines, we can rapidly produce ultraprecision optical components. FTI’s scientists and skilled staff routinely mold optics ranging from 250 µm in diameter to > 750 mm long—in batches of one to millions.
In addition to our lens design and manufacturing capabilities, FTI’s experts assist customers in optimizing their optical-grade polymer selections. We work with almost every optical polymer, including proprietary resins, and the range of our material choices spans the spectrum from ultraviolet (UV), through the visible, near-IR, and into the far-IR.
All optics from FTI are backed by validation testing. From off-the-shelf to fully custom optics projects, we are dedicated to being the best partner for your application.
