The laser is only a pointer, it's actually looking at the infra-red energy
Different materials also have different emissivity and a correction factor must
be used. Shiny rotors are one of these materials that can throw them off so
don't expect too much accuracy there. Check them with your regular pyrometer
as well as the Raytek and see what the correction factor will be.
The Raytek MiniTemp is actually set for the e-EMISSIVITY or rubber so it should
be fairly accurate there.
