A fabrication method of a transparent resin substrate comprises the steps melting a resin, mixing said resin with a first Phthalocyanine pigment (A) comprising a first minimum value of a first spectral transmission curve with a transmittance less than 10% within 800nm - 850nm wavelength; mixing said resin with a second Phthalocyanine pigment (B) comprising a second minimum value of a second spectral transmission curve with a transmittance less than 10% within 950nm - 1000nm wavelength; mixing said resin with a third Phthalocyanine pigment (C) comprising a third minimum value of a third spectral transmission curve with a transmittance less than 10% within 875nm - 925nm wavelength; injection molding of said mixed resin in a cavity; and obtaining a transparent resin substrate comprising an overall spectral transmission curve having within 800nm - 1000nm wavelength a minimum value area with a transmittance less than 5%, wherein an overall weight portion of the first Phthalocyanine pigment (A), the second Phthalocyanine pigment (B) and the third Phthalocyanine pigment (C) compared to the total substrate weight of the transparent resin substrate is in the range of 0.1 ppm - 50 ppm. |
