Abstract
An optical device may comprise an array of sensor elements that includes a plurality of pixels and a multispectral filter disposed on the array of sensor elements. The multispectral filter may be configured to pass a first transmission percentage of light of a particular spectral range to a first set of pixels of the plurality of pixels and pass a second transmission percentage of light of the particular spectral range to a second set of pixels of the plurality of pixels.

A multispectral filter comprising:
- one or more optical channels comprising an optical channel,
- the optical channel comprising a plurality of optical channel sections,
- the plurality of optical channel sections comprising:
- a first section configured to pass a first transmission of light of a particular spectral range to a first set of pixels of an array of sensor elements, and
- a second section configured to pass a second transmission of light of the particular spectral range to a second set of pixels of the array of sensor elements,
- an amount of the second transmission of light being greater than zero, and
- an amount of the first transmission of light being greater than the amount of the second transmission of light.
