| 摘要 |
The present invention provides an optical filter and an imaging device comprising the optical filter, the optical filter comprising: a binder resin; a light absorption layer containing at least two kinds of light absorbents dispersed in the binder resin; and a near-infrared reflection layer, wherein the light absorbents comprise a first light absorbent having maximum absorption in a wavelength range of 680 to 700nm and a second light absorbent having maximum absorption in a wavelength range of 700 to 750nm, and the near-infrared reflection layer has a wavelength, which has a transmittance of 50% with regard to light incident in a direction perpendicular to the optical filter, existing in a range of 680 to 730nm and satisfies equation 1 below: ΔE* ≤ 1.5 (equation 1) wherein ΔE* refers to 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. |
