Abstract:
Provided is a lens structure, comprising a lens barrel (1) and a lens group (2); the lens group (2) at least comprises a first lens (21) and a second lens (22); the first lens (21) comprises a first main body part (211) and a first supporting abutting part (212); the second lens (22) comprises a second main body part (221) and a second supporting abutting part (222); a light propagation space is formed between the first main body part (211) and the second main body part (221); the lens structure also comprises a light-blocking component (3) sandwiched between the first lens (21) and the second lens (22); the light-blocking component (3) comprises a light-blocking barrel (31) and an assembly part (32); the light-blocking barrel (31) has a first wall surface (311), a second wall surface (312), and a top surface (313); an assembly structure (02) is provided on the side of the first supporting abutting part (212) adjacent to the second lens (22); the assembly part (32) abuts against the assembly structure (02); the abutting surface (313) abuts against the second supporting abutting part (222); the first wall surface (311) is enclosed outside the light propagation space. The light-blocking component (3) has a simple assembly method and ensures assembly accuracy, while the light-blocking component (3) can also absorb stray light, ensuring good performance in absorbing stray light, thereby improving the quality of photographing of the lens structure.
