Description

光學影像鏡頭、取像裝置及電子裝置 Optical image lens, imaging device and electronic device

本發明係關於一種光學影像鏡頭及取像裝置，特別是關於一種具有可吸收長波長紅光的光學鏡片並可應用在電子裝置上的小型化光學影像鏡頭及取像裝置。 The invention relates to an optical image lens and an imaging device, in particular to a miniaturized optical image lens and an imaging device which can absorb long-wavelength red light and can be applied to electronic devices.

現有彩色影像感測元件於藍頻道與綠頻道在650~700nm之長波長紅光與700nm~1000nm之紅外光區域會有響應增加現象，這部分光線未濾除將會造成影像色再現及色飽和度不佳。 Existing color image sensing devices will have increased response in the blue and green channels in the long wavelength red light of 650~700nm and the infrared light region of 700nm~1000nm.

傳統習知技術使用紅外線濾除鍍膜濾鏡(IR Cut Coating Filter，以下簡稱IRCF)或紅外光吸收平板(俗稱藍玻璃，以下簡稱BG)，以將650nm以上的長波長紅光及近紅外光濾除，但所述方式有其缺陷，雖紅外線濾除鍍膜濾鏡具成本優勢，但當入射光角度加大時，其濾除波長會向短波長方向移動，使周邊紅光入光量降低，造成周邊區域相對中心區域色偏現象。而紅外光吸收平板之中心/周邊色偏問題，較紅外線濾除鍍膜濾鏡輕微，但成本高昂且受限於材 質種類，無法充分濾除紅外光，仍需配置紅外線濾除鍍膜於紅外光吸收平板上。 Conventional conventional technology uses infrared cut coating filter (IRCF) or infrared light absorption plate (commonly known as blue glass, hereinafter referred to as BG) to filter long-wavelength red light above 650nm and near infrared light In addition, the above method has its drawbacks. Although the infrared filter has a cost advantage, when the angle of incident light is increased, the filter wavelength will move to the short wavelength direction, which reduces the amount of incident red light. The color deviation of the surrounding area relative to the central area. The center/peripheral color shift problem of the infrared light absorption plate is less than that of the infrared filter coating filter, but the cost is high and limited by the type of material, which cannot fully filter out infrared light. It is still necessary to configure the infrared filter coating film for infrared light absorption On a tablet.

銫基氧化物材料亦可用以替代紅外線濾除鍍膜，如氧化鎢銫化合物(CsWOx)，其可設置於光學鏡片的表面或均勻散佈於光學鏡片中，以達到紅外光的濾除效果，且對可見光具低吸收效果，當光學影像鏡頭內使用所述材料時則可選擇性的取代紅外線濾除鍍膜280。 Cesium-based oxide materials can also be used to replace infrared filter coatings, such as tungsten oxide cesium compound (CsWOx), which can be placed on the surface of the optical lens or evenly distributed in the optical lens to achieve the infrared light filtering effect and Visible light has a low absorption effect, and when the material is used in the optical image lens, it can selectively replace the infrared filter coating 280.

光學影像鏡頭的FNO為1.80，光學影像鏡頭的最大CRA為35.0度，光學影像鏡頭的TTL/IMGH為1.48。 The FNO of the optical image lens is 1.80, the maximum CRA of the optical image lens is 35.0 degrees, and the TTL/IMGH of the optical image lens is 1.48.
