Near infrared light-cutting optical articles with low residual color
Abstract:
The present invention relates to an optical article having a substrate made of an optical material comprising a polymer matrix and at least one near infrared absorber, wherein TVIS is higher than or equal to 70%, TNIR is lower than or equal to 85%, TNIR and TVIS being respectively the average optical transmittance in the 780-1400 nm and in the 380-780 nm wavelength range for the optical material through a 2 mm thick layer of said optical material. This optical article can be used to protect from noxious infrared light.
