1. An optical filter, comprising:
a first component filter associated with a first wavelength of light; and
a second component filter associated with a second wavelength of light,
wherein the first wavelength of light is different from the second wavelength of light, and
wherein a size of the first component filter is based on one or more of:
an input flux from the second wavelength of light,
a cross-sectional area of the second component filter,
a filter responsivity of the second component filter to directing a wavelength toward a sensor element, or
a sensor responsivity of the sensor element at the second wavelength of light.
