Abstract: An optical filter comprising a light absorption layer and a near-infrared reflection layer, and an imaging device comprising the optical filter are provided. Wherein the light absorption layer has an absorption maximum in a wavelength range of 670 to 720 nm, a wavelength at which the near-infrared reflection layer has a light transmittance of 50% is in a range of 690 to 720 nm, and the optical filter satisfies the following Mathematical Formula 1: ΔE*≤1.5  [Mathematical Formula 1] wherein the ΔE* value represents a color difference between light that is incident in a vertical direction of the optical filter and passes through the optical filter and light that is incident at an angle of 30° with respect to the vertical direction of the optical filter and passes through the optical filter.
