These lenses have application in solar power such as focusing sunlight on a solar panel.
Solar power concentrated photovoltaic systems.
A solar concentrator diy can seem like the easiest thing in the world if someone else is doing the hard work.
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.
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.
