Abstract

The application discloses an optical imaging system, which comprises a first lens, a second lens, a third lens, a first prism, and a second prism which are sequentially arranged from an object side along a first direction. The first prism reflects light incident to the first prism along the first direction to be emitted from the first prism along a second direction; the second prism is arranged ina second direction and reflects light emitted from the first prism and incident to the second prism in the second direction into light emitted from the second prism in a third direction, and the first direction, the second direction and the third direction are perpendicular to one another; and the total effective focal length f of the optical imaging system meets the condition that f is larger than 20 mm.

Description

technical field [0001] The present application relates to the field of optical elements, in particular, to an optical imaging system. Background technique [0002] With the improvement of the imaging function requirements of smart phones and other miniaturized electronic product terminals, the hardware conditions of electrically coupled devices or complementary metal oxide semiconductor image sensors and the optical performance of imaging lenses have also been raised in the market. higher requirements. At present, miniaturized electronic product terminals such as smartphones tend to pursue a higher optical zoom factor. When the optical zoom factor value increases, the magnification of the optical imaging system will increase, making it more clearly visible when shooting distant objects. [0003] However, when the focal length of the system increases, the total optical length will also increase accordingly, which will have an adverse effect on the miniaturization of miniatu...
