Abstract
An optical lens assembly includes a sensor array, a lens array, and a shading element. The sensor array has a plurality of sensors arranged as a matrix to convert optical signals into electrical signals. The lens array has a plurality of lens units arranged as a matrix. The lens array is provided on the sensor array, and the lens units are aligned with the sensors to focus light onto the sensors respectively. The lens units are made of a light curable material or a thermosetting material, and separated from each other to form a trench between each two of the neighboring lens units. The shading element is received in the trenches of the lens array to avoid light which goes into any one of the lens units from entering into the other lens units.

A method of making an array type lens module, comprising the steps of:
- A. forming a lens member, wherein the lens member is made of a light curable material or a thermosetting material, and has a plurality of lens units;
- B. removing portions of the lens member between the lens units to form trenches between the lens units;
- C. providing a shading element in the trenches to avoid light which goes into any one of the lens units from entering into the other lens units;
- and
- D. cutting the lens member along with the shading element to obtain a plurality of the array type lens modules;
- wherein the trenches extend from a top to a bottom of the lens member to totally separate the lens units from each other.
An array type lens module, comprising:
- a lens array having a plurality of lens units to change an optical character of light going therethrough, wherein the lens units are arranged as a matrix, and separated from each other to form a trench between each two of the neighboring lens units;
- and
- a shading element received in the trenches of the lens array to avoid light which goes into any one of the lens units from entering into the other lens units;
- wherein the trenches extend from a top to a bottom of the lens member to totally separate the lens units from each other.
