^aOptical Density at 800 nm from Manufacturer either with sample or extracted from website

^bNo filter thickness provided on supplier’s websites so nominal measured thickness (d) supplied

^c“Y” in Dam columns signifies damage to sample was observed (discoloration or distortion) during the course of several seconds of exposure under the experimental conditions specified in the preceding column

^d“Inf” = infinity; signifies measured OD exceeds the system dynamic range maximum value
