1. An optical filter comprising:
a first row including only a first set of optical channels associated with a first wavelength range; and
a second row including only a second set of optical channels associated with a second wavelength range,
wherein:
a first optical channel, of the first set of optical channels, is configured to pass light associated with a subrange of the first wavelength range to a first sensor element of an optical sensor that is configured to detect light associated with the first wavelength range, and
a second optical channel, of the second set of optical channels, is configured to pass light associated with a subrange of the second wavelength range to a second sensor element of the optical sensor that is configured to detect light associated with the second wavelength range.
