Line Generating Fresnel Lenses

One side of the line-generating Fresnel lens is an optical plane, and the other side is composed of a series of strip-shaped optical surfaces. Each optical surface has a different angle, but they all focus the light on a line to form a linear focus. Each optical surface can be regarded as an independent lens, adjusting the light into parallel linear light and emitting it. Tianyang Valley offers a variety of sector-shaped angular line-generating Fresnel lenses. Line-generating Fresnel lenses can produce uniform energy distribution along the line for laser alignment and machine vision applications. Solar Valley uses high-precision high-temperature molding machines and ultra-high-precision molds to perform high-temperature molding on glass glass materials to produce high-precision line-generated Fresnel lenses. The advantages are low production cost, high precision, and suitable for mass production.
