A lens and its manufacturing method for increasing the beam propagation, scattering and convergence angle

Abstract

The invention provides a lens and a manufacturing method for increasing the beam propagation, scattering, and convergence angles, including: a curved surface, one side of the curved surface is provided with several groups of concave-convex mirrors, each group of concave mirrors is connected with a convex mirror, and the curved surface There are several areas on one side, and a group of concave-convex mirrors are respectively provided. The radial height of the concave mirror in each group is greater than the radial height of the convex mirror. The present invention combines the principle of geometric projection to analyze the light beam when it is incident The change distribution of the incident angle of the surface simulates the high-order continuous curve of the incident longitudinal section to design a reasonable combination of "concave / convex lens"; through optical software simulation, the beam diffusion effect is verified, and the incident surface is continuously adjusted for optimization; after that Using PC as the material, an infrared light source with a wavelength of 960nm provides light beams, conduct experiments on the designed lens, and then optimize the design; finally, the FFT.Ken lens is proposed.

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...
