一种摄像头模组和终端制造技术

一种摄像头模组和终端，该摄像头模组包括：光学保护窗(110)、红外截止滤光片(140)和抗反射涂层(220)；该抗反射涂层(220)位于光线经过的该光学保护窗(110)的至少一个表面，或该抗反射涂层(220)位于光线经过的该红外截止滤光片(140)的至少一个表面；该抗反射涂层(220)包括若干锥形抗反射结构(221)；该锥形抗反射结构(221)的底部直径为(D1)40nm～150nm；该锥形抗反射结构(221)的顶部直径(D2)为该底部直径(D1)的0～30％；该锥形抗反射结构(221)的高度(H0)为150nm～300nm；相邻两个该锥形抗反射结构(221)的间距为可见光波段波长的1/5～1/3。上述具有抗反射涂层(220)的摄像头模组，能够减少光线反射，有效抑制拍照中的鬼影和眩光问题。

Camera module and terminal

A camera module and a terminal, the camera module includes an optical protection window (110), infrared cut-off filter (140) and anti reflection coating (220); the anti reflective coating (220) is located in the light through the optical window of protection (110) at least one surface, or the anti reflective coating (220) is located in the infrared light through the filter (140) at least one surface; the anti reflective coating (220) comprises a plurality of conical anti reflective structure (221); the tapered anti reflection structure (221) of the bottom diameter (D1) 40nm ~ 150nm; the tapered anti reflection structure (221) of the top the diameter (D2) of the base diameter (D1) from 0 to 30%; the tapered anti reflection structure (221) height (H0) ranged from 150nm to 300nm; the two adjacent the tapered anti reflection structure (221) spacing for the wavelength of visible light 1/5 ~ 1/3. The camera module with anti reflection coating (220) can reduce the reflection of light, and effectively suppress the ghost and glare in the photograph.
