Abstract
A lens includes a substrate and an infrared-cut (IR-cut) filtering film. The substrate is made of sapphire, is configured for converging or diffusing light rays and includes an object-side surface and an image-side surface opposite to the object-side surface. The IR-cut filtering film increases the reflectivity of the substrate in relation to infrared light, and is coated on the image-side surface of the substrate.
