Abstract
Combining a tristimulus filter, two lenses, and a crystalline colloidal ay filter in an arrangement resulting in a visible optical limiter without substantial color distortion that can be used for eye or sensor protection. Only three nonlinear colloidal arrays are needed to Bragg reflect over the pass bands of the tristimulus filter. The nonlinear colloidal array is arranged so that the band reflected (at the least) completely overlaps the pass band of the tristimulus filter.
