Abstract: An optical filter may comprise a first pair of mirrors, a second pair of mirrors, and a common spacer. The second pair of mirrors and the first pair of mirrors may reflect different portions of an electromagnetic spectrum. The common spacer may be positioned between the first pair of mirrors and between the second pair of mirrors.

Abstract: A device may include an image sensor to capture an image using light in a visible range; and an optical filter to filter light received by the image sensor, wherein the optical filter passes light in the visible range, and wherein the optical filter absorbs or reflects light in a wavelength range of 830 to 1600 nanometers (nm). An optical filter may include a layer that passes light in the visible range, and one or more filter elements, wherein the optical filter is absorptive or reflective of light in the wavelength range of 830 to 1600 nm. Numerous other aspects are provided.
