Abstract

The present invention relates to the optical lens technology field, especially to an optical lens without optical return. The lens is made of the raw materials, parts by weight, consisting of the quartz sand of 52-58 parts, the alum of 4-8 parts, the sodium carbonate of 10-13 parts, the nanometer silicon dioxide of 4-6 parts, the modified graphene of 8-12 parts, the lithium hydrate of 4-6 parts, the hafnium boride of 7.5-8 parts, the potassium chloride of 8-10 parts, the vanadium pentoxide 5-8 parts, the iron carbide of 5-8 parts, the barium silicide of 4-6 parts, the tungsten silicide of 1-2 parts, the cobalt dioxide of 4-5.5 parts and the vitrification fiber of 2.5-3 parts. The lens is good in the diffraction to the ray of light and very low in optical return, is very suitable for the shooting usage in the highlight, and is low in the lens image drifting.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a lossless optical lens and a preparation process thereof. Background technique [0002] The optical lens is an essential part of the machine vision system, which directly affects the quality of the image and affects the realization and effect of the algorithm. Optical lenses can be divided into short-focus lenses, medium-focus lenses, and telephoto lenses in terms of focal length; wide-angle, standard, and telephoto lenses in terms of field of view; fixed-aperture fixed-focus lenses and manual aperture fixed-focus lenses in terms of structure. Auto-iris fixed-focus lenses, manual zoom lenses, auto-zoom lenses, auto-iris electric zoom lenses, electric three-variable (aperture, focal length, and focus) lenses, etc. The current optical lens has a large light loss due to the limitation of its material. Contents of the invention [0003] The technical problem to be solved ...
