Embodiments of the present disclosure disclose an optical imaging system, comprising, sequentially from an object side to an image side along an optical axis: a prism, reflecting light incident to the prism along a first direction, to cause the light to emerge from the prism along a second direction, and a stop, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens sequentially from the prism to an image side along the second direction, each of the first lens to the seventh lens has a refractive power. A total effective focal length f of the optical imaging system and an entrance pupil diameter EPIC of the optical imaging system satisfy: f/EPD<1.4.

Optical imaging system

The present disclosure discloses an optical imaging lens assembly including, sequentially from an object side to an image side along an optical axis, a first lens having positive refractive power and a concave image-side surface; a second lens having refractive power and a concave image-side surface; a third lens having refractive power; a fourth lens having refractive power; a fifth lens having positive refractive power; a sixth lens having refractive power, a convex object-side surface and a concave image-side surface; and a seventh lens having refractive power and a concave object-side surface. Half of a maximum field-of-view HFOV of the optical imaging lens assembly and a total effective focal length f of the optical imaging lens assembly satisfy: tan(HFOV)*f≥4.34 mm.
