Linear Fresnel Lens for solar concentrator

Solar concentrator linear fresnel lens has been developed for collecting parallel light to a slit form. The solar concentrator linear fresnel lenses are designed its plano side to face the sun (parallel light source), and the fresnel surface to face photovoltaic cells or heat collector tube (focus) as described 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 focus and the fresnel surface faces parallel light source.

NTKJ manufactures and sells not only Linear Fresnel lens products on the catalog, but also manufactures custom made Linear Fresnel lens products according to our customers' requirements in sizes and design. Please contact us for more details.

LFxxx-BH is fractionized linear Fresnel lens. For example, LF1000-BH has a focal length of 1000 mm. The size of one segment is 500 x 500 mm, and of 3 mm thickness, when two pieces are connected, they will form one 1000W x 500L linear Fresnel lens.
