Excitation and emission-scanning tunable filters used in this study (VersaChrome®, Semrock Inc., Rochester, New York). An array of filters was used for each tuning approach. The arrays were placed in custom housings, allowing translation between filters and rotation of each filter.15 Excitation-scanning filters were configured to allow a wavelength-tuning range from 357.9 to 707.6 nm, and emission-scanning filters were configured to allow a wavelength-tuning range from 398.4 to 710.0 nm.
