An optical device includes an optical sensor, a dye-based optical filter, and a multi-bandpass optical interference filter. The multi-bandpass optical interference filter is configured to pass a first spectral range of visible light, a second spectral range of visible light, and a third spectral range of visible light.

An optical filter (1a) includes a light-absorbing layer (10). The light-absorbing layer absorbs light in at least a portion of the near-infrared region. When light with a wavelength of 300 to 1200 nm is incident on the optical filter (1a) at an incident angle of 0°, the optical filter (1a) satisfies given requirements.
