## Abstract

The present disclosure provides a lens. The lens includes: an optical portion at a central position; and a bearing portion surrounding the optical portion. The bearing portion includes a first surface, a second surface opposite to the first surface, and a connection surface connecting the first surface with the second surface. The first surface is provided with a first arc surface and a first planar surface. An intersection line between the first arc surface and the first planar surface is a first feature circle for measuring an interfacial decenter. The second surface is provided with a second arc surface and a second planar surface. An intersection line between the second arc surface and the second planar surface is a second feature circle for measuring the interfacial decenter. A radius of the first feature circle is not equal to a radius of the second feature circle.

## Claims

### Claim 1

A lens, comprising:
an optical portion at a central position; and
a bearing portion surrounding the optical portion,
wherein the bearing portion comprises a first surface, a second surface opposite to the first surface, and a connection surface connecting the first surface with the second surface; the first surface is provided with a first arc surface and a first planar surface; an intersection line between the first arc surface and the first planar surface is a first feature circle for measuring an interfacial decenter; the second surface is provided with a second arc surface and a second planar surface; an intersection line between the second arc surface and the second planar surface is a second feature circle for measuring the interfacial decenter; a radius of the first feature circle is not equal to a radius of the second feature circle, wherein a first angle between a tangent plane of the first arc surface at the first feature circle and the first planar surface is smaller than or equal to 10° and a second angle between a tangent plane of the second arc surface at the second feature circle and the second planar surface is smaller than or equal to 10°.

### Claim 2 (depends on 1)

The lens as described in claim 1, wherein the lens is made of glass.

### Claim 3 (depends on 1)

The lens as described in claim 1, wherein the optical portion comprises an object-side surface close to an object side and an image-side surface opposite to the object-side surface, and the first surface is further provided with a first protruding portion arc-connected to the object-side surface.
