Fresnel Lens

About Tecnottica Consonni srl

• Type: Lenses

A Fresnel lens is an optical element that can be used as an alternative to the classical optical lenses with continuous surfaces. Its principle of operation is relatively simple: starting from the assumption that the refractive power of a lens is inherent within its optical interfaces (i.e. its surface), you can remove much of the material that forms the optical surface while maintaining the curvature of the original one. A second point of view may be to consider the continuous surface of a lens as collapsed on a plane. We can obtain spherical, aspherical, cylindrical Fresnel lenses and so on.

Tecnottica offers to its customers two types of Fresnel lenses: glass-molded Fresnel lenses (with the possibility of having the flat back surface polished or satin) and plastic-molded Fresnel lenses. We have a large production of many kinds of Fresnel lenses, divided by their focal lengths and geometries, and we also produce customizable Fresnel lenses in according to specific customer’s requests.
