Patent ID: 8246259

Claim:
A camera module, comprising: a lens barrel defining an aperture for light to enter the lens barrel; and a lens received in the lens barrel, the lens comprising a central optical portion aligned with the aperture of the lens barrel and a fixing portion around a periphery of the optical portion for fixing the lens in the lens barrel; wherein an outside surface of the fixing portion comprises an object-side surface, an image-side surface, and a lateral-side surface interconnecting the image-side surface and the object-side surface; wherein the lateral-side surface has a circular frustoconical shape with a diameter decreasing gradually from where the lateral-side surface connects with the object-side surface to where the lateral-side surface connects with the image-side surface, whereby the entire lateral-side surface is beveled relative to an optical axis of the camera module to be able to reduce or avoid total internal reflection of the light at the lateral-side surface; and wherein the image-side surface and the object-side surface of the fixing portion of the lens are parallel to each other, and are beveled relative to the optical axis of the camera module.
