IR-CUT FILTER HAVING RED ABSORBING LAYER FOR DIGITAL CAMERA

摘要

An infrared cut filter may be used with an image sensor to remove infrared light components from image light received from a first side of the infrared cut filter prior to the image light reaching the image sensor to be disposed on a second side of the infrared cut filter. The infrared cut filter includes at least one red absorbing layer and an infrared reflector. The at least one red absorbing layer partially absorbs red light components within the image light. The infrared reflector reflects the infrared light components. The infrared reflector is disposed between the red absorbing layer and the first side of the infrared cut filter while the at least one red absorbing layer is disposed between the infrared reflector and the second side of the infrared cut filter.
