Abstract

An optical element includes a lens component and a filter. The lens component has first, second, third, fourth, fifth, sixth and seventh surfaces disposed around and parallel to a reference axis. The lens component further has spaced apart first and second collimating units formed on the first surface, and a third collimating unit formed on the second surface. The second collimating unit is located between the first and third collimating units. The third surface is formed with a groove defined by the fourth, fifth, sixth and seventh surfaces. The filter is disposed on the third surface, covers the groove, and has a first side surface facing the fourth, fifth, sixth and seventh surfaces, and a second side surface opposite to the first side surface.
