Optical filter and imaging device

An optical filter, comprising:

• a first absorption layer comprising a near-infrared absorbing dye and a transparent resin;
• and a reflection layer,
• wherein the first absorption layer has a thickness of 0.3 μm to 10 μm, and
• wherein the optical filter satisfies the following (ii-2) to (ii-6):
• (ii-2) an average transmittance T435-480 ave0° of light in a wavelength range of 435 to 480 nm is 70% or more at an incident angle of 0 degrees,
• (ii-3) an average transmittance T490-580 ave0° light in a wavelength range of 490 to 580 nm is 84% or more at an incident angle of 0 degrees,
• (ii-4) an average transmittance T800-900 ave60° of light in a wavelength range of 800 to 900 nm is 0.1% or less at an incident angle of 60 degrees,
• (ii-5) a maximum transmittance T800-900max60° of light in a wavelength range of 800 to 900 nm is 2.1% or less at an incident angle of 60 degrees, and
• (ii-6) a wavelength λSHT20-0° that is a shorter wavelength of wavelengths showing a transmittance of 20% at an incident angle of 0 degrees is in a wavelength range of 640 to 690 nm, and a difference between a wavelength λSHT20-30° that is a shorter wavelength of wavelengths showing a transmittance of 20% at an incident angle 30 degrees and the wavelength λSHT20-0° is 10 nm or less.
