Abstract
An antireflective infrared cut filter coating may be applied on transparent substrates within electronic devices, such as sapphire or glass substrates. The transparent substrates may be windows for optical components or may be cover glasses for displays. The antireflective infrared cut filter coating may be formed from a thin-film interference filter having a plurality of thin-film layers of varying materials and thicknesses. The antireflective infrared cut filter coating may transmit light neutrally across visible wavelengths and may reflect infrared light. In this way, the antireflective infrared cut filter coating may reduce unwanted infrared light from reaching underlying optical components, such as wide-angle cameras, thereby reducing undesirable artifacts in images generated by the components.
