Abstract

The invention discloses a lens, a method for removing lens flare and a die for manufacturing a lens barrel. The lens comprises the lens barrel and a first lens sheet, a second lens sheet and an infrared light filter which are arranged in the lens barrel in turn, wherein the surface of at least one of the first lens sheet, the first lens sheet and the infrared light filter is provided with a coating film for reducing ray reflection. The lens, the method for removing the lens flare and the die for manufacturing the lens barrel can increase the permeability of the lens, weaken the ray reflection,and effectively inhibit the production of the flare.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a lens, a method for removing lens glare and a mold for manufacturing a lens barrel of the lens. Background technique [0002] Optical imaging devices are prone to glare during the imaging process, which affects the brightness and clarity of imaging. There are many reasons for glare. [0003] For a lens under ideal conditions, light can completely pass through the lens to reach the photosensitive medium. However, in actual situations, when the light passes through the front and rear surfaces of the lens, not only refraction but also reflection will occur. Part of the light will be reflected on the surface of the lens, reducing the light reaching the photosensitive medium, resulting in a decrease in image quality and a decrease in the brightness of the image. At the same time, because the lens is assembled from several groups of different lenses, the light will produce g...
