Detailed below are the
filter sets that utilise Alpha Technology for the emission filters.
This results in much steeper edges than any other filter
manufacturing method, while increasing attenuation and virtually
eliminating auto-fluorescence. Excitation filters use a bandpass
filter design as in Vivid Class and Vivid Standard sets. Dichroics
are hard surface coated. Emission fiters are ALPHA longpass designs.
Vivid Plus sets provide the brightest images for most fluorescent
dyes, with less colour definition than the ALPHA Vivid Sets.
