Description

光學鏡頭、取像裝置及電子裝置Optical lenses, imaging devices and electronic devices

本揭示內容是有關於一種光學鏡頭及取像裝置，且特別是有關於一種應用於電子裝置中並可濾除紅外線的光學鏡頭及取像裝置。The present disclosure relates to an optical lens and an imaging device, and in particular, to an optical lens and an imaging device that are used in electronic devices and can filter out infrared rays.

光學鏡頭由鏡片群和影像感測元件所組成，其中，影像感測元件由於會感測可見光以外的紅外光，因此需要設置紅外線濾除元件。習知作法是在平板元件上鍍膜來濾除紅外線，以避免紅外線感應而導致色偏，但由於反射式的鍍膜技術是採用干涉原理，其在大角度入射光處會產生反射漏光，習知作法會再以吸收式藍玻璃來解決漏光問題。The optical lens is composed of a lens group and an image sensing element. Since the image sensing element can sense infrared light other than visible light, it needs to be equipped with an infrared filter element. The common practice is to coat flat components to filter out infrared rays to avoid color cast caused by infrared ray induction. However, since the reflective coating technology uses the interference principle, it will produce reflected light leakage at large angles of incident light. We will use absorptive blue glass to solve the light leakage problem.

因此更發展出直接在藍玻璃表面製作紅外線濾除鍍膜的技術，以達到減少元件之目標，然而，具有鍍膜的藍玻璃元件成本高、微型化困難且容易碎裂。雖紅外線濾除鍍膜也可製作在塑膠鏡片表面，卻未能有效解決大角度漏光的缺陷，光線通過塑膠鏡片表面的濾除鍍膜後，會在光線大角度入射處發生較光線垂直入射的中心處更為嚴重的反射現象，鏡片離軸處的大角度入射光線會造成穿透率的波段偏移，而產生漏光反射問題。光學系統內的反射光線漫射後，將使非預期的光線進入感測元件內成像，而造成干擾真實色彩的色偏問題，因此藍玻璃仍遲遲無法被取代。Therefore, the technology of making an infrared filtering coating directly on the surface of blue glass has been developed to achieve the goal of reducing components. However, coated blue glass components are costly, difficult to miniaturize, and prone to breakage. Although infrared filtering coatings can also be made on the surface of plastic lenses, they cannot effectively solve the problem of light leakage at large angles. After light passes through the filtering coating on the surface of plastic lenses, light will occur at the center where the light is incident at a large angle than at the center where the light is vertically incident. For more serious reflection phenomena, the large angle of incident light off the axis of the lens will cause the transmittance to shift in the band, resulting in light leakage and reflection problems. After the reflected light in the optical system is diffused, unintended light will enter the sensing element and form an image, causing a color cast that interferes with the true color. Therefore, blue glass still cannot be replaced.

再者，通常在離軸處且靠近最大有效徑範圍處的光線會導致帶通波段偏移的情況，進而造成影像色均勻度不佳之問題。當紅外線濾除鍍膜被製作在曲率半徑變化劇烈的鏡片表面時，會使光線穿透濾除鍍膜的反射角度的變化更難以控制。Furthermore, the light that is usually off-axis and close to the maximum effective diameter range will cause the bandpass band to shift, thereby causing the problem of poor image color uniformity. When the infrared filter coating is made on the surface of a lens whose radius of curvature changes drastically, it will be more difficult to control the change in the reflection angle of light penetrating the filter coating.

隨著成像品質要求提升，鏡片數量相應增加，以獲得較佳的成像品質與較佳的像差修正效果。為使鏡頭成像色彩更接近真實並獲得鏡頭尺寸微小化的優勢，需發展減少光學系統中元件數量的方式，在減除藍玻璃平板元件時勢必得研發替代技術，因此亟需可減少元件數量，並具有高影像品質的創新技術。As imaging quality requirements increase, the number of lenses increases accordingly to obtain better imaging quality and better aberration correction effects. In order to make the imaging color of the lens closer to reality and gain the advantage of miniaturizing the lens size, it is necessary to develop ways to reduce the number of components in the optical system. When removing blue glass flat components, it is necessary to develop alternative technologies. Therefore, there is an urgent need to reduce the number of components and Innovative technology with high image quality.

傳統光學鏡頭由物側至像側依序包含一光學系統110、一平板玻璃130b及一電子感光元件150b，平板玻璃130b的物側表面具有一抗反射膜層120b。詳言之，傳統光學鏡頭的平板玻璃130b設置方式為平板玻璃130b與電子感光元件150b的一表面140b（成像面）間有一空氣間距，最大像高視場處的主光線入射平板玻璃130b的表面的角度為α（即CRAg），當主光線經平板玻璃130b折射後會變成角度較小的β，而主光線出射於平板玻璃130b再經空氣折射後會變回原有角度α（即CRA），當主光線角過大時會導致光線無法順利入射電子感光元件150b，或造成畫素錯位響應而產生色偏而降低成像品質。A traditional optical lens includes an optical system 110, a flat glass 130b and an electronic photosensitive element 150b in order from the object side to the image side. The object side surface of the flat glass 130b has an anti-reflective film layer 120b. In detail, the flat glass 130b of the traditional optical lens is arranged in such a way that there is an air gap between the flat glass 130b and a surface 140b (imaging surface) of the electronic photosensitive element 150b, and the chief ray at the maximum image high field of view is incident on the surface of the flat glass 130b. The angle is α (that is, CRAg). When the chief ray is refracted by the flat glass 130b, it will change to a smaller angle β, and the chief ray emerges from the flat glass 130b and will change back to the original angle α (that is, CRA) after being refracted by the air. , when the chief ray angle is too large, the light will not be smoothly incident on the electronic photosensitive element 150b, or the pixels will be misaligned in response, resulting in color shift and reduced imaging quality.

本揭示內容的光學鏡頭由物側至像側可以依序包含一光學系統110、一平板玻璃130a及一電子感光元件150a，平板玻璃130a的物側表面具有一抗反射膜層120a。詳言之，本揭示內容的光學鏡頭的平板玻璃130a設置方式為平板玻璃130a直接設置於電子感光元件150a的一表面140a，最大像高視場處的主光線入射平板玻璃130a的表面的角度為α（即CRAg），當主光線經平板玻璃130a折射後會變成角度β，因平板玻璃130a與電子感光元件150a表面140a間無空氣間距，主光線得以用較小的角度β（即CRA）直接入射於電子感光元件150a，本揭示內容的光學鏡頭設計可有效避免傳統大角度光線無法成像與色偏的問題，並具有降低主光線角度、減少後焦長、縮減光學鏡頭總長度、縮小最大像高與製程簡化等優勢。The optical lens of the present disclosure may include an optical system 110, a flat glass 130a and an electronic photosensitive element 150a in sequence from the object side to the image side. The object side surface of the flat glass 130a has an anti-reflective film layer 120a. In detail, the flat glass 130a of the optical lens of the present disclosure is arranged in such a manner that the flat glass 130a is directly arranged on a surface 140a of the electronic photosensitive element 150a. The angle at which the chief ray at the maximum image high field of view enters the surface of the flat glass 130a is α (i.e. CRAg), when the chief ray is refracted by the flat glass 130a, it will become an angle β. Since there is no air gap between the flat glass 130a and the surface 140a of the electronic photosensitive element 150a, the main ray can be directed at a smaller angle β (i.e. CRA) Incident to the electronic photosensitive element 150a, the optical lens design disclosed in this disclosure can effectively avoid the problems of traditional large-angle light being unable to image and color cast, and has the advantages of lowering the main ray angle, reducing the back focal length, reducing the total length of the optical lens, and reducing the maximum image. High efficiency and process simplification.
