An optical element includes a lens component and a filter. The lens component has a first plane, a second plane, a third plane, a fourth plane, a fifth plane, a first collimating unit formed on the first plane, a second collimating unit formed on the first plane, and a third collimating unit formed on the third plane. The first, second, third, fourth and fifth planes are disposed around and parallel to a reference axis. The third plane is formed with a groove defined by a sixth plane and a seventh plane which extend obliquely from the third plane and respectively opposite to the first and second planes. Each of the sixth and seventh planes extends in a direction that is parallel to the reference axis. The filter is disposed on the third plane for covering the groove.
