Description

光學攝像透鏡組、成像裝置及電子裝置Optical camera lens group, imaging device and electronic device

本創作係有關於一種光學攝像透鏡組及成像裝置,特別是有關於適用於車用攝影電子裝置或監控攝影系統之光學攝像透鏡組及成像裝置。This creation relates to an optical camera lens group and imaging device, in particular, to an optical camera lens group and imaging device suitable for a vehicle photography electronic device or a surveillance camera system.

近年來,由於數位化電子產品的普及,包括數位相機、筆記型電腦、手機、平板等,帶動了光學鏡頭模組的蓬勃發展。為了適用於各種不同的用途,例如智慧型手機、運動型攝影機、行車記錄器、倒車攝影裝置、及家用監控攝影設備等,對於光學鏡頭模組的品質需求也日益提高。In recent years, due to the popularity of digital electronic products, including digital cameras, notebook computers, mobile phones, tablets, etc., has driven the vigorous development of optical lens modules. In order to be suitable for various applications, such as smart phones, sports cameras, driving recorders, reversing camera devices, and home surveillance camera equipment, the demand for the quality of optical lens modules is also increasing.

除了逐漸朝向小型化的發展,光學鏡頭模組亦要求更寬廣的拍照視野及良好的成像品質。然而,提高光學鏡頭模組的成像視角,常會導致透鏡組的總長度增加(體積變大),或者使得像差變得難以修正。以美國專利7,623,305號為例,其包含具有負屈折力之第一鏡群、光圈及具有正屈折力之第二鏡群;第一鏡群包含具有負屈折力之第一透鏡及具有正屈折力之第二透鏡;第二鏡群包含具有正屈折力之第三透鏡、具有負屈折力之第四透鏡及具有正屈折力之第五透鏡。雖然在此專利所揭露的光學透鏡組架構下,可以有效縮小鏡頭成像的畸變像差,但其拍攝視角僅能達到70度左右,無法符合現今消費者的使用需求。In addition to the gradual development towards miniaturization, optical lens modules also require a wider field of view and good imaging quality. However, increasing the imaging angle of the optical lens module often causes the total length of the lens group to increase (the volume becomes larger), or makes the aberration difficult to correct. Taking US Patent No. 7,623,305 as an example, it includes a first lens group with negative refractive power, an aperture, and a second lens group with positive refractive power; the first lens group includes a first lens with negative refractive power and a positive refractive power The second lens; the second lens group includes a third lens with positive refractive power, a fourth lens with negative refractive power, and a fifth lens with positive refractive power. Although the optical lens assembly structure disclosed in this patent can effectively reduce the distortion aberration of the lens imaging, its shooting angle can only reach about 70 degrees, which cannot meet the needs of today's consumers.

是以,如何提供一種廣視角且具有良好成像品質的小型光學鏡頭模組已成為此技術領域之人士亟欲解決之問題。Therefore, how to provide a small optical lens module with a wide viewing angle and good imaging quality has become a problem that people in this technical field are eager to solve.

參見圖10B,圖中由左至右分別為光學攝像透鏡組1000之縱向球差圖、像散像差圖及畸變像差圖。由縱向球差圖可以看出,三種近紅外光900nm、940nm、980nm波長在不同高度的離軸光線皆可集中於成像點附近,其成像點偏差可以控制在 +0.05mm以內。由像散像差圖(波長940nm)可以看出,弧矢方向的像散像差在整個視場範圍內的焦距變化量在 +0.04mm以內;子午方向的像散像差在整個視場範圍內的焦距變化量在 +0.04mm以內;而畸變像差可以控制在15%以內。如圖10B所示,本實施例之光學攝像透鏡組1000已良好地修正了各項像差,符合光學系統的成像品質要求。 第十一實施例 Referring to FIG. 10B, from left to right in the figure are a longitudinal spherical aberration diagram, an astigmatic aberration diagram, and a distortion aberration diagram of the optical imaging lens group 1000, respectively. From the longitudinal spherical aberration diagram, it can be seen that the three near-infrared rays of 900nm, 940nm, and 980nm at different heights can be concentrated near the imaging point, and the deviation of the imaging point can be controlled within + 0.05mm. It can be seen from the astigmatic aberration diagram (wavelength 940nm) that the sagittal aberration aberration varies within + 0.04mm of the focal length in the entire field of view; the meridional astigmatism aberration in the entire field of view The focal length variation within is within + 0.04mm; and the distortion aberration can be controlled within 15%. As shown in FIG. 10B, the optical imaging lens group 1000 of this embodiment has corrected various aberrations well, which meets the imaging quality requirements of the optical system.
