Abstract

Portions of a lens barrel for an optical imaging system can be coated with an optical thin-film coating to prevent unwanted light, such as flare, from reaching an image sensor. The optical thin-film coating can be a multi-layered structure formed from alternating layers of a low-refractive-index material and a high-refractive-index material. The coating can have low absolute reflectance (e.g., less than 1% across the wavelength range of visible light) and can be applied to a front surface and / or other surfaces of a lens barrel.

Description

technical field [0001] The invention relates to a lens barrel, in particular to a low-reflection lens barrel and a lens module using the lens barrel. Background technique [0002] Portable electronic products such as mobile phones, digital cameras, and tablet computers are all equipped with an image module. Sensors and other components on the imaging surface of the lens. The reflected light from the surface of the object outside the lens barrel can be guided through the cooperation of the lenses and focused on the sensor on the imaging surface, so that the image module achieves the effect of image capture. In some designs, the reflected light on the surface of the lens barrel can be guided by the lenses and projected onto the sensor, causing the image captured by the sensor to have defect patterns such as flares, thereby reducing the image quality obtained by the image module. image quality. Contents of the invention [0003] Therefore, the object of the present inventi...
