1. A method of evaluating quality of graphene using a confocal laser scanning microscope, the method comprising steps of:
irradiating with laser light a graphene layer formed on a catalyst layer;
detecting a signal of light reflected from the graphene layer;
forming a planar image of the graphene layer using the detected optical signal; and
analyzing a contrast between graphene and the catalyst layer in the planar image, wherein the graphene layer is continuously formed on the catalyst layer by a roll-to-roll process.
