Abstract

An optical lens including a lens and at least one optical layer is provided. The lens has a central region and a peripheral region surrounding the central region. The at least one optical layer is disposed on the lens. Each optical layer is located in the peripheral region and exposes the central region, wherein the peripheral region has at least one first gap strip region connected to the central region, and each optical layer exposes the at least one first gap strip region. A fixture is also provided.

First claim

What is claimed is:

1 . An optical lens, comprising:
a lens, having a central region and a peripheral region surrounding the central region; and at least one optical layer, disposed on the lens, each optical layer located in the peripheral region and exposing the central region, wherein the peripheral region has at least one first gap strip region connected to the central region, and each optical layer exposes the at least one first gap strip region.

2 . The optical lens according to claim 1 , wherein a point connecting each first gap strip region and the central region is defined as a first connecting point, a straight line passing through the first connecting point from a center of the lens along a radial direction is defined as a first radius line, an angle between orthogonal projections of each first gap strip region and the first radius line on a reference plane which is vertical to an optical axis direction of the optical lens is within a range of 30 degrees to 60 degrees.

3 . The optical lens according to claim 1 , wherein each first gap strip region is connected between the central region and a peripheral edge of the lens.

4 . The optical lens according to claim 1 , wherein the peripheral region further has at least one second gap strip region not connected to the central region, and each optical layer further exposes the at least one second gap strip region.

5 . The optical lens according to claim 4 , wherein each first gap strip region is connected between the central region and a peripheral edge of the lens, each second gap strip region is connected to the peripheral edge of the lens.

6 . The optical lens according to claim 1 , wherein a shape of each first gap strip region is straight strip shape.

7 . A fixture, adapted to fix the lens of the optical lens during a process of manufacturing the optical lens as claimed in claim 1 , the fixture comprises:
a carrier plate, having at least one opening; a shielding plate, located in the opening and shielding the central region of the lens; and at least one first connecting portion, connecting the carrier plate and the shielding plate, wherein the at least one first connecting portion supports the peripheral region of the lens and shields the at least one first gap strip region.

8 . The fixture according to claim 7 , wherein a point connecting each first connecting portion and the shielding plate is defined as a second connecting point, a straight line passing through the second connecting point from a center of the shielding plate along a radial direction is defined as a second radius line, an angle between orthogonal projections of each first connecting portion and the second radius line on a reference plane which is vertical to an optical axis direction of the optical lens is within a range of 30 degrees to 60 degrees.

9 . The fixture according to claim 7 , wherein an inner radius of the carrier plate is larger than a diameter of the lens.

10 . The fixture according to claim 7 , further comprises:
at least one second connecting portion, located in the opening, connected to the carrier plate, and not connected to the shielding plate, wherein the at least one second connecting portion supports the peripheral region of the lens and defines at least one second gap strip region not connected to the central region in the peripheral region.

11 . The fixture according to claim 7 , wherein a shape of each first connecting portion is straight strip shape.
