Abstract

The utility model discloses a mobile phone front lens, which comprises an optical fiber bundle and a first lens group, wherein the optical fiber bundle is configured to enable the light incident into the optical fiber bundle along the direction of a Y optical axis to be reflected and then emitted out of the optical fiber bundle along the direction of an X optical axis, and the X optical axis is vertical to the Y optical axis; the first mirror group is fixedly arranged on the incident surface of the optical fiber bundle along the Y optical axis; the mobile phone front lens further comprises a second lens group from the optical fiber bundle to the imaging surface along the X optical axis. In the conventional mobile phone lens in the market, because a plurality of lenses are continuously stacked on the same optical axis, when a long focal length is required, the thickness of the lens in the optical axis direction is inevitably increased, so that the size of the lens is overlarge. The mobile phone front lens in the technical scheme of the application is provided with the arc-shaped optical fiber bundle, so that the X optical axis and the Y optical axis are perpendicular to each other, the requirement of a long focal length or a long back focal length can be met, and the size and the thickness of the lens can not be increased.
