About solar concentrator linear Fresnel lenses
Solar concentrator linear Fresnel lenses were developed to collect parallel light to a slit form. Solar concentrator linear Fresnel lenses are designed so that the plano side faces the sun (parallel light source), and the Fresnel surface faces photovoltaic cells or a heat collector tube (focus) as shown in the diagram below.
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 linear Fresnel lenses, but also manufactures custom-made Linear Fresnel lens products according to our customers’ size and design requirements. Please contact us for more details.
