Solar concentrator Fresnel lens / Sensor Fresnel lens

About solar concentrator Fresnel lenses and Fresnel lenses for sensors 

Solar concentrator Fresnel lenses were originally developed for concentrating photovoltaic (CPV) application. The solar concentrator Fresnel lenses are designed with the plano side to face the sun (parallel light source), and the Fresnel surface to face photovoltaic cells (focus). These lenses are also used as a solar energy concentrator for solar furnaces.

This configuration is designed to collect parallel light onto a spot, shorter focal length fresnel lenses can be used for detection purposes in combination with sensors and/or detectors.

Our standard Fresnel lenses can also be used for the same purposes but with the opposite facing design. Namely, its plano side faces the focus and the Fresnel surface faces the parallel light source.

NTKJ manufactures and sells not only off-the-shelf solar concentrator Fresnel lenses, but also manufactures custom-made solar concentrator Fresnel lens products according to our customers’ exact size and design requirements. Please contact us for more details.
