Abstract
An electronic device may be provided with one or more light-sensing components such as a camera and a color ambient light sensor. Optical structures such as camera lenses or a light pipe may be used to convey light from a window in an electronic device to a light-sensing component. One or more infrared-light-blocking-and-visible-light transmitting light filters may be interposed between a light-receiving window in an electronic device and a light-sensing component. The light filters may include infrared-light-blocking glass substrates, silver or other infrared-light-blocking thin films, and/or thin-film interference filters formed from stacks of dielectric layers that serve as infrared light-blocking layers.
