These lenses have application in solar power such as focusing sunlight on a solar panel.
Fresnel lens and solar panel.
By concentrating solar power onto solar cells they can increase the amount of sun striking the solar cell and allow a relatively small amount of silicon photovoltaic pv material to be used in large solar panels.
Solar power concentrated photovoltaic systems.
Such a lens can focus light on a small spot but does not produce a sharp image.
A fresnel lens is a lens with multiple refracting planes designed to improve the concentration of light coming from many different angles onto a single point or line.
