Abstract: Disclosed are optical elements that contains two or more near infrared absorbers and methods of producing the same. Two near infrared absorbers with different near infrared wavelengths absorption ranges and residual colors are mixed with a precursor of an optical substrate. The resulting mixture is subsequently processed to produce optical elements that have a broad near infrared wavelength absorption range and a neutral residual color.
