    摘要： The present disclosure discloses an optical lens assembly including a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens, which are arranged sequentially from an object side to an image side along an optical axis. The first lens has negative refractive power, an object-side surface thereof is convex, and an image-side surface thereof is concave. The second lens has negative refractive power, an object-side surface thereof is convex, and an image-side surface thereof is concave. The third lens has positive refractive power, and both of an object-side surface and an image-side surface thereof are convex. The fourth lens has refractive power. The fifth lens and the sixth lens are cemented to form a cemented lens. The seventh lens has positive refractive power, and both of an object-side surface and an image-side surface thereof are convex.

    摘要： An image lens assembly includes four lens groups: a first lens group, a second lens group, a third lens group and a fourth lens group along an optical path. The four lens groups include nine lens elements: a first lens element with positive refractive power, a second lens element with negative refractive power, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, a seventh lens element, an eighth lens element and a ninth lens element along the optical path. At least one lens element of the image lens assembly has at least one inflection point. At least five lens elements of the image lens assembly are made of plastic material. When focusing or zooming, the first lens group and the fourth lens group stay stationary, while the second lens group and the third lens group move along an optical axis.

    摘要： The objective lens for an endoscope consists of, in order from an object side, a first lens group consisting of one negative lens, a second lens group consisting of two lenses cemented together, a stop, a third lens group consisting of two lenses that have refractive powers with different signs and are cemented together, and a fourth lens group consisting of two lenses that have refractive powers with different signs and are cemented together. The objective lens for an endoscope satisfies a predetermined conditional expression regarding an Abbe number, a length of a lens system, and the like.
