Optical image capturing lens

An optical image capturing lens, comprising:

• a first lens positioning unit, wherein an interior of the first lens positioning unit is hollow, and the first lens positioning unit is made of an opaque material;
• one end of the first lens positioning unit has an object-side opening;
• an imaging lens assembly installed within the first lens positioning unit, wherein the imaging lens assembly, along an optical axis from an object side to an image side starting from the object-side opening, comprises a first lens, a second lens, and an image plane;
• the first lens and the second lens each have refractive power;
• the first lens has a first optical effective area and a first optical ineffective area;
• the first optical effective area is surrounded by the first optical ineffective area;
• the second lens has a second optical effective area and a second optical ineffective area;
• the second optical effective area faces the first optical effective area, and the second optical effective area is surrounded by the second optical ineffective area;
• the image plane is located on one side of the second lens opposite to the object-side opening and the first lens;
• wherein the optical axis passes through the first lens and the second lens respectively via the first optical effective area and the second optical effective area;
• the first lens defines a first maximum effective diameter at the first optical effective area, and the second lens defines a second maximum effective diameter at the second optical effective area;
• and
• at least one light entrance member made of an opaque material, wherein the at least one light entrance member is installed within the first lens positioning unit;
• the at least one light entrance member surrounds the optical axis and is located between the first lens and second lens;
• the at least one light entrance member is disposed on a side of the first optical ineffective area of the first lens facing the second optical ineffective area of the second lens;
• the at least one light entrance member has a light entrance hole facing the first optical effective area and the second optical effective area to allow the optical axis to pass through;
• a diameter of the light entrance hole is smaller than or equal to the first maximum effective diameter of the first lens and is smaller than or equal to the second maximum effective diameter of the second lens.
