  • Patent number: 8355216
    Abstract: An image forming lens includes a lens element having a flange part that is integral with the lens element. When assembled with an image pickup element to form an image pickup module, an outside perimeter portion of the lens element having a flange part, at a region nearest an image pickup element, is inclined so that outer diameters thereof increase when successively measured at positions nearer to the image pickup element. A frame of the image forming lens according to the invention has an inclined portion on the object side with an outer diameter that becomes smaller when successively measured nearer the object side. Satisfying one or more conditions insures accuracy in assembly and that there will be sufficient room near the object side outside the inclined portion to mount a light source, such as an LED, without having to increase the maximum outer diameter of the image pickup module.
