Abstract
A spectrophotometer includes a plurality of sensor elements arranged together, each sensor element including a filter; a light sensor optically coupled with an output of the filter; and a barrier that surrounds the filter and light sensor and a space between the filter and light sensor. For each sensor element, the barrier blocks light that has not passed through the filter from reaching the light sensor including such that light from one sensor element is not detected by another of the sensor elements.
