An optical device may include an optical filter disposed over a first surface of one or more substrates. The optical filter may include an aperture and may be configured to pass light that is received via the aperture and that is associated with one or more wavelength ranges via the one or more substrates based on an angle of incidence of the light on the optical filter. The optical device may include one or more optical elements disposed over a second surface of the one or more substrates that are configured to direct light beams of the light that are associated with a particular wavelength range, of the one or more wavelength ranges, to a particular set of sensor elements of an optical sensor. The optical filter may include a thin film optical interference filter and the one or more optical elements may include one or more metamaterial structures.
