Disclosed is a 4K laparoscope objective lens with a 30° viewing angle, comprising a crescent concave lens (1), a prism combination (2), a triplet cemented lens (3), a cemented lens (4), a first crescent rear lens (5), and a second crescent rear lens (6) which are sequentially cemented in a light propagation direction, wherein one side of the crescent concave lens (1) is a convex surface, and the other side thereof is an even aspheric surface； one side of the triplet cemented lens (3) is a plane, and the other side thereof is a convex surface； both sides of the cemented lens (4) are convex surfaces； and one side of each of the first crescent rear lens (5) and the second crescent rear lens (6) is a concave surface, and the other sides thereof are both convex surfaces. The even aspheric surface of the crescent concave lens (1) is cemented to one side of the prism combination (2), the other side of the prism combination (2) is cemented to the plane of the triplet cemented lens (3), the convex surface of the triplet cemented lens (3) is cemented to the convex surface on one side of the cemented lens (4), the convex surface on the other side of the cemented lens (4) is cemented to the first crescent rear lens (5), and the concave surface of the first crescent rear lens (5) and the concave surface of the second crescent rear lens (6) are oppositely cemented into a whole. The objective lens is suitable for a laparoscope with a 30° viewing angle, and achieves a 4K high-definition resolution rate.La présente invention concerne une lentille d'objectif de laparoscope 4K ayant un angle de vision de 30 °, comprenant une lentille concave en croissant (1), une combinaison de prisme (2), une lentille cimentée en triplet (3), une lentille cimentée (4), une première lentille arrière en croissant (5), et une seconde lentille arrière en croissant (6) qui sont séquentiellement cimentées dans un sens de propagation de la lumière, un côté de la lentille concave en croissant (1) étant une s
