OPTICAL LENS AND A METHOD FOR MANUFACTURING THE SAME

摘要

An optical lens includes a barrel and a protruding boss unit. The barrel defines a receiving space in which a plurality of components are disposed and arranged along an axis, and includes a front wall. Each of the front wall and the components has front and rear confronting surfaces opposite to each other along the axis. The protruding boss unit is formed on and protrudes from one of the adjacent two front and rear confronting surfaces, and abuts against the other one of the adjacent two front and rear confronting surfaces. The other one of the front and rear confronting surfaces abutted by the boss unit is flat.

主权项

1. An optical lens comprising:
a barrel including a front wall formed with an aperture that surrounds an optical axis, said barrel defining a receiving space; a lens assembly including a plurality of components that are disposed in said receiving space and that are arranged along the optical axis, each of said front wall and said components having front and rear confronting surfaces that are opposite to each other along the optical axis; a plurality of annular confronting-surface pairs, wherein one of said annular confronting-surface pairs is disposed between said front wall of said barrel and one of said components, which is in closest proximity to said front wall, and consists of said rear confronting surface of said front wall and said front confronting surface of said one of said components, wherein each of the other ones of said annular confronting-surface pairs is disposed between adjacent two of said components, and consists of said front confronting surface of a rear one of said adjacent two of said components and said rear confronting surface of a front one of said adjacent two of said components; and at least one protruding boss unit formed on one of said front and rear confronting surfaces of one of said annular confronting-surface pairs, and including at least one boss element that protrudes from said one of said front and rear confronting surfaces along a direction parallel to the optical axis and that abuts against the other one of said front and rear confronting surfaces of said one of said annular confronting-surface pairs, the other one of said front and rear confronting surfaces abutted by the protruding boss unit being flat.
