[0003] However, between the ultra-precision processed aspheric area of the lens and the lens structure, there is a small area (the area gradually transitioning from the optical part to the non-optical part). Because of the optical design of the lens, the spacer ring cannot fit the lens tightly and the spacer ring cannot Block stray light, which will cause glare in the lens module and affect the image quality

Embodiment Construction
[0029] see figure 1 and figure 2 The lens module 10 provided by the embodiment of the present invention includes a lens barrel 11 , a first lens 12 , a spacer ring 13 , a second lens 14 and an image sensor 15 , wherein the second lens 14 is close to the image sensor 15 . The light is imaged on the image sensor 15 through the first lens 12 and the second lens 14 .
[0030] Certainly, the lens module 10 may also include other optical components such as a third lens, a filter, etc. so that the lens module 10 has different functions.
[0031] The first lens 12 and the second lens 14 are adjacently arranged in the lens barrel 11 and the optical axes are both L, and the spacer ring 13 is located between the first lens 12 and the second lens 14 for spacing the first lens 12 and the second lens 14 Two mirrors 14.
[0032] The first lens 12 includes an optical part 120 , a non-optical part 121 and a connecting part 122 , and the connecting part 122 is located between the optical pa...

A spacer ring, located between adjacent first lenses and second lenses in a lens module for spacing the first lenses and second lenses, the first lens has an optical axis and includes an optical part, a non-optical part and a connecting part, the non-optical part is substantially perpendicular to the optical axis, the connecting part includes a connecting surface, the connecting surface, the spacer ring includes a spacer part and a light shielding part, and the spacer part is in contact with the non-optical part Contacting to space the first lens and the second lens, the shading part includes an engaging surface, the engaging surface has an angle greater than 0 degrees and less than 90 degrees with the optical axis and has an angle matching the connecting surface The structure is used to cover the connecting portion. The present invention also relates to a lens module with the spacer ring.
Description
technical field [0001] The invention relates to a lens module. Background technique [0002] In the lens module, a spacer ring is usually added to space adjacent lenses and block the generation of stray light (flare). [0003] However, between the ultra-precision processed aspheric area of the lens and the lens structure, there is a small area (the area gradually transitioning from the optical part to the non-optical part). Because of the optical design of the lens, the spacer ring cannot fit the lens tightly and the spacer ring cannot Block stray light, which will cause glare to the lens module and affect the image quality. Contents of the invention [0004] In view of this, it is necessary to provide a spacer ring for blocking stray light and a lens module with the spacer ring. [0005] A spacer ring, located between the adjacent first lens and second lens in the lens module, is used to space the first lens and the second lens, the first lens is located on the object...
