    Abstract: An optical pen is disclosed. The handwriting input pen includes a housing, a light source module received in the housing, an optical lens, a pen tip. The light source module is configured for emitting light. The optical lens is configured for converging light emitted from the light source module, the optical lens comprising an optical portion and a supporting portion around the optical portion. The pen tip is positioned at an end of the housing and is configured for guiding light out of the housing to project. The shielding member is around the optical portion attached to the optical lens and covering the supporting portion of the optical lens, and is configured for stopping the light passing through the supporting portion from entering into the pen tips.
