Fluoresbrite® Polychromatic Red Microspheres will fluoresce in different colors, depending on the light source and filters used. When viewed under a UV light source, the beads will appear as vivid orange. Microscopic viewing using a 475-490nm filter shows an extremely bright red fluorescence, while use of a 545-610nm filter yields a yellow fluorescence with excitation maxima of 491nm and 512nm and emission maxima at 554nm.
