Abstract
Provided is a supporting element having an object-side mechanical surface, an image-side mechanical surface, an inner-side connecting surface having a first and a second plane inner walls extending from at least one of the object-side and the image-side mechanical surfaces, and an outer-side connecting surface having a first and a second outer cutting surfaces respectively adjacent to the first and the second plane inner walls. The supporting element satisfies the following conditional expression. 4≤R/SD≤30. R represents half of a distance between the first and the second outer cutting surfaces. SD represents a smaller one of a first and a second distances, the former being the minimum distance between the first outer cutting surface and the first plane inner wall, the latter being the minimum distance between the second outer cutting surface and the second plane inner wall. A portable optical imaging lens is also provided.
