Custom Fresnel Lenses

Fresnel lenses replace conventional lenses that have a curved surface with a series of concentric grooves, which are moulded into the surface of lightweight plastic sheets. The moulded grooves act as individual refracting surfaces when viewed in cross section. These lightweight large-aperture Fresnel lenses are widely used as collimators and collectors, e.g. in sensor or communication systems. We stock two grades a general purpose grade and a precision grade that are manufactured to tighter tolerances.

Knight Optical can offer Custom Fresnel Lenses and also offer other focal lengths and sizes from available alternative stock. We can also make custom lenses as new tooling is also available. Whether you have a prototype application or a production run requirement to your unique specification, we are able to accommodate these needs.
