Fresnel lenses are usually made from a lightweight PMMA Acrylic unless used in high energy applications such as lighthouses or power stations where heat resistant borosilicate material would be suitable.
Fresnel lenses have one side machined with spaced concentric steps. Each step acts as a refractive surface similar to a prism. This produces a common focal length as in a traditional spherical lens without the weight of a traditional glass lens. Fresnel lenses are typical used for collimators and collectors in communication systems, sensors and projectors. Supplied as spherical form for or cylindrical types for focusing a line.

Specification:
Focal length: 5%
Surface quality: 80-50 scratch/ dig
Typical materials: PMMA Acrylic, Borosilicate or equivalent material. UV grade acrylic
