Patent ID: 10114155

Abstract:
An optical filter and an imaging device comprising the optical filter are provided. The optical filet comprises: a binder resin; a light absorption containing at least two kinds of light absorbents dispersed in the binder resin; and a near-infrared reflection layer. Further, the light absorbents comprise a first light absorbent having maximum absorption in a wavelength range of 680 to 700 nm and a second light absorbent having maximum absorption in a wavelength range of 700 to 750 nm, a wavelength at which the near-infrared reflection layer has a transmittance of 50% with regard to light incident in a direction perpendicular to the optical filter is in a range of 680 to 730 nm, and the optical filter satisfies [Equation 1] ΔE*≤1.5, wherein ΔE* represents a color difference between light, which has been incident in a direction perpendicular to the optical filter and has passed through the optical filter, and light, which has been incident at an angle of 30° with regard to the direction perpendicular to the optical filter and has passed through the optical filter.
