Those links to data sheets are of complete polygon mirror motor
assemblies. You supply 24V and then point a laser on them. I don't think
I can fabricate anything close to such precision. The mirrors flatness
and symmetry are absolutely critical. They look like mass produced
items so I don't think they should be expensive. But where ?
This mob specialises in polygon mirror motor assemblies. They have lots
of technical application notes too.
