Kind Code:
A1
Abstract:
A lens assembly (100), a camera module (10), a terminal (1) and an assembly method for a lens assembly (100), the lens assembly comprising: a first lens (110), comprising a first lens barrel (111) and a first lens group (112), an image side surface of the first lens group (112) being a first surface (1121), and the first surface (1121) being provided with a first connecting part; and a second lens (120), located at an image side of the first lens (110), the second lens (120) comprising a second lens barrel (121) and a second lens group (122), an object side surface of the second lens group (122) being a second surface (1221), the second surface (1221) being provided with a second connecting part, and the second connecting part being adjustably connected to the first connecting part. An image side surface of the first lens barrel (111) is a third surface (1111), and an object side surface of the second lens barrel (121) is a fourth surface (1211). The second lens (120) has a second optical axis (n), and the orthographic projection of the third surface (1111) on a reference surface (123) on which the second optical axis (n) is located is a first projection (11111); the orthographic projection of the fourth surface (1211) on the reference surface (123) is a second projection (12111), and the first projection (11111) and the second projection (12111) do not coincide. The resolution of the lens assembly (100) can be improved, and the adjustable range is large enough.
