Optical Microscope (OM) to determine graphite alkene panels and graphite alkene reflex optical strength of different caused a contrast differences to tell the difference between floors, also by silicon base plate thickness of the different carbon-level.

Light microscope (OM) determines the contrast gradient difference which the graphite alkene foundation plate and the graphite alkene reflection light intensity different creates to distinguish the layer, also may by xi the foundation plate on the different thickness oxide layer.

Optical microscope (OM) to determine Graphene substrate and Graphene's reflected light intensity caused by contrast differences to distinguish between layers, or by varying the thickness of the oxide layer on Si substrate.
