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.
Abstract:
A lens adapter ring is provided for connecting a lens barrel to a lens holder whose thread specification is different from that of the lens barrel. The ring includes a first hollow cylinder. The cylinder includes a first inner surface and a first outer surface opposite to the first inner surface. The first outer surface includes a first outer thread portion adapted for the lens holder, and the first inner surface includes a first inner thread portion adapted for the lens barrel. The thread specification of the first outer thread portion is different from that of the inner thread portion. A lens module using the lens adapter ring is also provided.

Abstract:
A camera module includes a lens barrel and a lens holder. The lens barrel includes a first tubular section and a second tubular section. The first tubular section extends from an end of the second tubular section. The outer diameter of the first tubular section tapers in a direction from the image side to the object side of the lens barrel. The lens holder includes a third tubular section and a fourth tubular section. The third tubular section extends from an end of the fourth tubular section. The outer diameter of the third tubular section tapers in a direction from an image side to an object side of the third tubular section. The lens barrel threadedly inserts into the lens holder and is held by the lens holder.
