摘要:
A compact camera lens composed of the following five lenses in this sequence proceeding from the object side: a first positive meniscus lens, wherein the concave surface of the first positive meniscus lens faces away from the object side; a second negative lens, wherein the object-side surface of the second negative lens is concave; a third positive lens, wherein the image-side surface of the third positive lens is convex; a fourth biconvex lens; and a fifth negative lens.The fourth biconvex lens and the fifth negative lens are in each case cemented with one another. The object-side surface of the third positive lens and the image-side surface of the fifth negative lens are of aspherical form. The objective is particularly robust, compact, has a large aperture and very good imaging characteristics. It is suitable for example as an objective of an exterior mirror replacement camera in the automotive field.
