Frequently Asked Questions
Fresnel lenses are used in laser optics, OEM, industrial, scientific, and metrology applications.
There are positive focal length Fresnel lenses used as collectors, positive focal length Fresnel lenses used as collimators, and negative focal length Fresnel lenses used as divergers.
The aspheric Fresnel lens was invented by Augustin Jean Fresnel in 1822.
The advantage of using a Fresnel lens is that it reduces the bulk of material between the refracting surfaces, making it more efficient and cost-effective.
Fresnel lenses are typically cut and polished in glass, but can also be made from other materials such as plastic or acrylic.
