Optical filter and imaging device
An optical filter includes: an absorption layer including a first near-infrared absorbing dye (D1), a second near-infrared absorbing dye (D2), and a transparent resin; and a reflection layer including a dielectric multilayer film. The dye (D1) and the dye (D2) are squarylium compounds satisfying following (1) to (3). (1) The dye (D1) has a maximum absorption wavelength λ.sub.max(D1) within a range of 680 to 730 nm, and the difference between a wavelength at which a transmittance is 80% on the shorter wavelength side than λ.sub.max(D1) when the concentration is adjusted such that a transmittance at λ.sub.max(D1) is 10%, and λ.sub.max(D1) is 100 nm or less. (2) The dye (D2) has a maximum absorption wavelength λ.sub.max(D2) within a range of 720 to 770 nm. (3) A value obtained by subtracting λ.sub.max(D1) from λ.sub.max(D2) is 30 nm or more and 85 nm or less.
OPTICAL IMAGE CAPTURING SYSTEM
