Fresnel cylindrical lens is an aspheric lens, which can effectively reduce spherical aberration and chromatic aberration. With one-dimensional zoom function.
Cylindrical mirrors are mainly used in the design requirements of changing the imaging size. For example, convert a point spot to a line spot, or change the height of the image without changing the width of the image.
Can be used in linear detector lighting, barcode scanning, holographic lighting, etc.
Fresnel cylindrical lens has the advantages of ultra-thin structure, super large size, ultra-light weight, arbitrary shape cutting, excellent light transmittance, low price, light and easy to carry, etc.
