Description
本發明係關於一種光學成像鏡頭及取像裝置，特別是關於一種包含可吸收限定波長之光線的塑膠光學鏡片，並可應用在電子裝置上的小型化光學成像鏡頭及取像裝置。 The present invention relates to an optical imaging lens and an imaging device, and more particularly to a miniaturized optical imaging lens and imaging device that includes a plastic optical lens that can absorb light of a limited wavelength and can be applied to an electronic device.
現有彩色影像感測元件能同時響應可見光、波長650nm~700nm的長波長紅光與波長700nm~1100nm的紅外光，因此造成色飽和度不佳與影像色彩失真。 The existing color image sensing element can simultaneously respond to visible light, long-wavelength red light with a wavelength of 650 nm to 700 nm, and infrared light with a wavelength of 700 nm to 1100 nm, thereby causing poor color saturation and image color distortion.
習用技術設置藍玻璃濾光片(紅外光吸收平板)可提供紅外光濾除效果，但成本高昂且受限於材質種類而無法充分濾除紅外光。再者，光線吸收式的濾光片需具有較大厚度，進而導致後焦距延長，且現今市場以多鏡片的鏡頭為主流，更造成高成像品質鏡頭的體積微型化不易。 The conventional technology provided with a blue glass filter (infrared light absorption flat panel) can provide infrared light filtering effect, but the cost is high and limited by the type of material, it cannot fully filter the infrared light. Furthermore, the light-absorbing filter needs to have a relatively large thickness, which results in an extension of the back focal length. In the current market, multi-lens lenses are the mainstream, which makes it difficult to miniaturize the volume of high-imaging quality lenses.
再者，高成像品質的多鏡片鏡頭為滿足微型化、非球面製造與量產需求，其鏡片皆選擇塑膠材質，但塑膠光學鏡片無法避免短波長光線，例如紫外光或藍光的損害 而產生劣化，導致耐用度與成像品質下降，雖有習用鍍膜技術可反射紫外光，但鍍膜成本高昂且有均勻性問題。 Furthermore, to meet the needs of miniaturization, aspheric manufacturing and mass production of high-quality multi-lens lenses, the lenses are made of plastic materials, but plastic optical lenses cannot avoid the deterioration of short-wavelength light, such as ultraviolet light or blue light. , Resulting in a decrease in durability and image quality. Although conventional coating technology can reflect ultraviolet light, the coating cost is high and there are problems with uniformity.
