Linear Fresnel lens

About linear Fresnel lenses

Linear Fresnel lenses are flat cylindrical lenses that condense or diffuse light in a linear direction. They are suitable for diffusing a linear light source or for slit collection. They are widely applied in linear light sources.

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