Thermo Fisher Scientific offers the Fluoro-Max beads in sizes up to 140 um, in green or red emission, which is at least at the lower end of your desired size range.  See here:

Dear All,

Does anyone know of a company who can supply fluorescent spheres in this size range suitable for confocal imaging? I know people are usually looking for standards at the other end of the scale!

I've had a look at Bangs Laboratories and Spherotech but they don't seem to have anything large enough...

Kind regards,

Jacqui
