Abstract

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. The second spectral range does not overlap with the first spectral range, and the third spectral range does not overlap with the first spectral range and the second spectral range. The multi-bandpass optical interference filter is further configured to prevent passage of a fourth spectral range of near-infrared light. An angle shift associated with each spectral range, of the first spectral range, the second spectral range, and the third spectral range, is less than or equal to 2.0% of a center wavelength of the spectral range for angles of incidence between 0 and 30 degrees.
