An optical imaging system according to an embodiment of the present disclosure includes a first lens, a second lens, and a third lens arranged in this order from an object side. In the optical imaging system according to the present embodiment, an air gap between the first lens and the second lens is larger than an air gap between the second lens and the third lens. Further, in the optical imaging system according to the present embodiment, the first lens is formed of a glass material, and a length of the first lens in a first direction intersecting the optical axis is different from a length of the first lens in a second direction intersecting the optical axis. 根据本公开的实施例的光学成像系统包括从物侧顺序布置的第一透镜、第二透镜和第三透镜。在根据本实施例的光学成像系统中，第一透镜和第二透镜之间的空气间隙大于第二透镜和第三透镜之间的空气间隙。此外，在根据本实施例的光学成像系统中，第一透镜由玻璃材料形成，并且第一透镜在与光轴相交的第一方向上的长度不同于第一透镜在与光轴相交的第二方向上的长度。
