Abstract

The invention provides a lens increasing the beam propagation scattering convergence angle and a manufacturing method thereof. The lens comprises a curved surface. Groups of concave-convex lenses are arranged on one side of the curved surface. In each group, a concave lens is connected with a convex lens. A number of regions are arranged on one side of the curved surface, and a group of concave-convex lens is arranged in a region. The radial height of each concave lens is greater than the radial height of each convex lens in each group. According to the invention, a geometric projection principle is combined to analyze the incident angle variation distribution of a beam on an incidence surface. The incidence longitudinal section high-order continuous curve is simulated to design a reasonable concave/convex lens combination. The beam diffusion effect is verified through optical software simulation. The incidence surface is constantly adjusted for optimization. An infrared light source made of PC is used to provide the beam, wherein the wavelength of the infrared light source is 960nm. Experiments are carried out on designed lens, and then optimization design is carried out. Finally, the FFT.Ken lens is provided.

Description

technical field [0001] The present invention relates to multiple fields such as light illumination, signal transmission, scientific and technological research, energy diffusion / convergence, etc., and specifically relates to a lens (FFT.Ken lens) and a manufacturing method that increases the angle of light beam propagation scattering / convergence based on optical principles. Background technique [0002] At present, the lenses aimed at expanding the scattering / converging angle of beam propagation are all based on the basic optical refraction and scattering principles, such as the most basic convex lens ( figure 1 ) and concave lens ( figure 2 ). [0003] On the basic optical principle, there is a Fresnel lens ( image 3 ). The Fresnel lens was invented by the French physicist Augustin.Fresnel. In 1822, he established a glass Fresnel lens system - "Lighthouse Lens" with this lens design. The working principle of this lens is to assume that the refractive energy of a lens o...
