    摘要： A lens for a LED light source includes a first light emitting surface and a light incident surface perpendicular to the optical axis of the lens. The first light emitting surface is a convex surface and opposite to the light incident surface. The lens further includes a second light emitting surface opposite to the light incident surface and adjacent to the first light emitting surface. The thickness between the second light emitting surface and the light incident surface near the optical axis exceeds the thickness between the second light emitting surface and the light incident surface away from the optical axis.

    摘要： A fingerprint identification assembly includes a laminated lens having a first lens, a second lens and a third lens formed together with the first lens and the second lens, each of the first lens, the second lens and the third lens has a dielectric film coated thereon. At least one illuminator is located at a bottom of the laminated lens and a sensor located under the laminated lens for picking up an image of a fingerprint on top of the laminated lens. The dielectric film of the laminated lens allows light from the at least one illuminator to be partially reflected due to the fingerprint on the laminated lens and partially penetrates through the second lens and the third lens to be picked up by the sensor.

    摘要： The present invention provides a kind of compact-thin contact image sensor, particularly a fingerprint optical input apparatus, which can extract fingerprint image with a strip-type sensor. And it can produce fingerprint image with high definition, and shorten its size with the multibend light pipe. In addition, it has an enough guiding length for forming a strip area distributed uniformly, and the light would project on the strip-type fingerprint pressed on a transparent panel from some angle and reflect to the strip-type sensors by total internal reflection. Lastly, the forest fingerprint image would be extracted by moving the finger.
