Abstract
A lens includes an optical portion configured to refract light, and a flange portion extending from the optical portion, wherein a first region having first surface roughness, a second region having second surface roughness, and a third region having third surface roughness are sequentially disposed from the optical portion toward the flange portion, on at least one of an object-side surface and an image-side surface of the flange portion, the first surface roughness and the third surface roughness are greater than the second surface roughness, and a light blocking portion is disposed in the second region.
Claims14
A lens, comprising:
- an optical portion configured to refract light;
- and
- a flange portion extending from the optical portion,
- wherein a first region having first surface roughness, a second region having second surface roughness, and a third region having third surface roughness are sequentially disposed from the optical portion toward the flange portion, on at least one of an object-side surface and an image-side surface of the flange portion,
- wherein the first surface roughness and the third surface roughness are greater than the second surface roughness,
- wherein a light blocking portion is disposed in the second region, and
- wherein the light blocking portion is disposed to extend from a surface of the second region to an inside of the flange portion.
A lens assembly, comprising:
- a plurality of lenses disposed along an optical axis, and respectively including an optical portion configured to refract light and a flange portion extending from the optical portion;
- and
- a lens barrel accommodating the plurality of lenses,
- wherein one or more lenses of the plurality of lenses include a light blocking portion disposed on a surface of the flange portion,
- wherein the light blocking portion is disposed at a position spaced apart from the optical portion by a predetermined distance,
- wherein the surface of the flange portion on which the light blocking portion is disposed has lower surface roughness than other surfaces of the flange portion, and
- wherein the light blocking portion is disposed to extend from the surface of the flange portion to an inside of the flange portion.
