Fresnel Technologies makes a variety of stock Fresnel and related optical components to meet your needs. We can also design and construct custom Fresnel lenses and polymer optics  as requested. Our Fresnel items fall into a number of categories, but they are all made from polymer materials. Generally, our engineers design these components with thicknesses under 1/4" (6 mm) with a stepped surface.

Our team of optical experts can help you bring your project to life with custom or off-the-shelf designs. We’re here to help you find the right solution.

Today's modern computer-controlled machining methods can be used to cut the surface of each cone precisely to bring all paraxial rays into focus at exactly the same point, avoiding spherical aberration. Better still, newer optical manufacturing methods can be used to cut each refracting surface in the correct aspheric contour (rather than as a conical approximation to this contour), thus avoiding even the width of the groove (typically 0.1 to 1 mm) as a limit to the sharpness of the focus. Even though each groove or facet brings light precisely to a focus, the breaking up the wavefront by the discontinuous surface of a Fresnel lens degrades the visible image quality. Except in certain situations, Fresnel lenses are usually not recommended for imaging applications in the visible light region of the spectrum.
