A chemical sensor includes a patterned layer having discrete sections, a two-dimensional detector array, and a two-dimensional lens array that focuses an optical signal from the patterned layer onto the two dimensional detector array. Typically, the two-dimensional detector array is a charge-coupled device array and the lens array is a graded index of refraction lens array. The chemical sensor maintains good resolution throughout its field of view.
