AI Technical Summary

Technical Problem

When sealing the internal space of the lens unit, the lens spacing deviation is easily caused by the amount of adhesive applied, or the lens deformation is caused by clamping the elastic material, which affects the optical performance.

Method used

Using a multi-layer sealing material structure, the first lens and the lens barrel are sealed through the first sealing material (O-ring), the second sealing material (O-ring) seals the lens barrel and the frame member, and the third sealing material (adhesive) seals the frame member and the N-th lens to avoid the negative impact of adhesive coating and elastic material clamping on the lens.

Benefits of technology

Effectively seal the internal space of the lens unit, avoid lens spacing deviation and optical surface deformation, and improve the stability of optical performance.

Abstract

The invention relates to a lens unit and a camera module which appropriately seal an internal space. A lens unit (1) is provided with: a plurality of lenses (20) including a first lens (21) closest to an object side and a fourth lens (24) closer to an image side than the first lens; a frame member (29) that holds the fourth lens (24); a lens barrel (3) that houses the plurality of lenses (20) and the frame member (29); a first sealing material (61) that seals a space between the first lens (21) and the lens barrel (3); a second sealing material (62) that seals between the lens barrel (3) and the frame member (29); and a third sealing material (63) that seals the space between the frame member (29) and the fourth lens (24).
