The Fresnel cylindrical mirror is an aspherical lens that can effectively reduce spherical aberration and chromatic aberration. Has a one-dimensional amplification function.
Cylindrical mirrors are primarily used to change the design requirements for imaging size. For example, converting a spot into a line spot,
Or change the height of the image without changing the image width.
Can be applied to linear detector illumination, barcode scanning, holographic lighting, etc .
Fresnel cylindrical mirror has: Fresnel lens ultra-thin structure, large size, ultra-light weight, cutting of any shape , excellent light transmittance, low price, light and easy to carry, etc.
