摘　　要：为了避免口腔内窥镜由于消毒不彻底造成的交叉感染问题,实现一次性口腔内窥镜的运用普及,设计了一款低成本、高成像质量的一次性口腔内窥镜,该口腔内窥镜焦距3.3 mm,F数为5.6,全视场62°,可见光波段成像,同时具有90°视向角方便口腔内部观察。通过在ZEMAX中优化设计,最终得到由1片玻璃透镜和5片塑料透镜构成的一次性口腔内窥镜,该内窥镜所有镜片均为球面镜,系统总长39.7 mm,光学传递函数在178 lp/mm大于0.2,接近衍射极限成像优良,总体设计满足实际运用需求。In order to avoid cross infection caused by inadequate disinfection problems of oral endoscope and realize the widespread use of disposable oral endoscope,a low-cost and high imaging quality disposable oral endoscope is designed.The oral endoscope has focal length of 3.3 mm,F number of 5.6,the whole field of 62°,the visible light wave band imaging,at the same time with 90°angle of view to convenient oral observation.Through the optimization design in ZEMAX,a disposable oral endoscope composed of 1 glass lens and 5 plastic lenses is finally obtained.All the lenses of the endoscope are spherical lens;the total length of the system is 39.7 mm;and the optical transfer function is greater than 0.2 at 178 lp/mm,which is close to the diffraction limit.The overall design meets the practical application requirements.
