For example, in the split type lens provided in at least one embodiment of the present application, as shown in fig. 1, 2, 4, and 5, the first outer side surface 112 extends to the first surface 114 along an inclined direction forming an included angle with an optical axis, that is, the diameter of a projection circle of the first outer side surface 112 on the first surface 114 gradually increases along an incident direction of light, so that the first outer side surface 112 of the first barrel 110 is inclined, a space is provided for dispensing at an abutting position of the abutting portion 111 and the limiting groove 400, and a dispensing operation space is prevented from being limited due to the fact that a glue needle is easily abutted against the first outer side surface 112 of the first barrel 110 when the first outer side surface 112 of the first barrel 110 is parallel to the optical axis direction of the lens; on the other hand, the first outer side surface 112 in the present application can increase a pushing force for the glue to slide down, which helps the glue to slide down along the first outer side surface 112; as shown in fig. 10, the inclination angle α of the first outer side surface 112 is greater than 10 °, so as to avoid demoulding due to an excessively small inclination angle.

For example, in the split lens provided in at least one embodiment of the present application, as shown in fig. 1, 2, 4, and 5, the abutting portion 111 is a step structure 113 protruding from the first outer side surface 112, the step structure 113 has an abutting step surface 1131, and an extending surface 1132 extending from the first outer side surface 112 to the abutting step surface 1131, and the sealing member 310 is connected to the abutting step surface 1131 and/or connected to the first surface 114. Through setting up stair structure 113, avoid first lateral surface 112 and the first surface 114 lug connection of first lens cone 110 to lead to the junction to form the closed angle, and then form the deckle edge easily and lead to the problem that the product size is not up to standard.

For example, in the split type lens provided in at least one embodiment of the present application, further, as shown in fig. 1-2, 4-5, and 7-8, the second barrel 210 further has a second through hole 230, a hole wall of the second through hole 230 forms an inner side surface, the second through hole 230 is a stepped hole, the stepped hole has an outer hole 231 with a larger diameter and an inner hole 232 with a smaller diameter, an annular inner stepped surface 211 is formed between a hole wall of the outer hole 232 and a hole wall of the inner hole 232, the second lens 220 abuts against the annular inner stepped surface 221, and the annular inner stepped surface 211 prevents glue from overflowing from the gap to the lens in the second barrel 210 due to an adhesive member 320 in the limiting groove 400.

The sealing member 310 and the bonding member 320 in the embodiment of the present application are UV thermosetting glue, but not limited to UV thermosetting glue, and photo-curable glue, moisture-curable glue, and the like may also be used.
