摘要： An optical imaging lens, including a first lens element, a second lens element, and a third lens element sequentially disposed from an object side to an image side along an optical axis, is provided. Each of the first lens element to the third lens element includes an object-side surface that faces the object side and allows an imaging ray to pass through, and an image-side surface that faces the image side and allowing the imaging ray to pass through. A periphery region of the image-side surface of the first lens element is concave. An optical axis region of the object-side surface of the second lens element is concave. The third lens element has negative refracting power. Lens elements of the optical imaging lens are only the above three lens elements, and the optical imaging lens satisfies the following conditional expressions: HFOV/TTL≥16.000 degrees/mm and T1/T3≥1.350.

摘要： A supporting element includes a light-shielding portion and a supporting portion connected to the light-shielding portion. The light-shielding portion has a first surface, a second surface, a first inner-side connecting surface, and a first outer-side connecting surface. The first inner-side connecting and outer-side connecting surfaces connect the first and second surfaces, and face toward the inside and outside of the supporting element respectively. The first surface and the second surface are curved surfaces, and the first inner-side connecting surface further includes a first light-shielding surface adjacent to the first surface. The supporting portion has a third surface, a fourth surface, a second inner-side connecting surface, and a second outer-side connecting surface. The second inner-side connecting surface and the second outer-side connecting surface connect the third and the fourth surfaces, and face toward the inside and outside of the supporting element respectively. Furthermore, a portable optical imaging lens is also provided.

摘要： An optical lens including a light-shielding sheet and a spacer sequentially arranged along an optical axis from a first side to a second side is provided. No other element is disposed between the light-shielding sheet and the spacer. A second side surface of the light-shielding sheet includes a first surface. A first side surface of the spacer includes an abutting surface and a connecting surface connected to each other, and the connecting surface has a protrusion portion. A cross-sectional line of the abutting surface of the spacer in a radial direction is a straight line and abuts against the first surface of the light-shielding sheet, and an abutment between the abutting surface and the first surface falls on a first reference plane. The light-shielding sheet and a most protruding portion of the protrusion portion are located on a same side of the first reference plane.
