Knight Optical provide specially designed Fresnel lenses of reverse configuration making them ideal for use in Solar Concentration such as concentration photovoltaic (CPV) application. They are designed in such a way that the plano side faces the sun and the Fresnel surface faces the photovoltaic cells to focus the light. Our Standard Fresnel Lenses can also be used in this manner, but are not optimised for this application so typically used in the opposite way.
A larger surface can be assembled using single lenses as segments, making it ideal for solar concentration.
Our stock range are manufactured from PMMA, and range from 100mmx100mm to 1400mmx1050mm.
