NOVELTY - The apparatus comprises an optical device, a graphite oxide layer formed on a surface of the optical device, a conveying part for conveying the optical device in a linear motion, and a controller for controlling optical properties and movement of the optical device by the conveying part. The optical device is configured for irradiating light on a substrate. The conveying unit moves horizontally the substrates in a longitudinal direction of the linear motion. The optical device comprises a compact-disk recording apparatus, and a DVD recording apparatus. USE - The apparatus is useful for manufacturing graphene (claimed). ADVANTAGE - The apparatus economically manufactures the graphene with high quality and productivity. DETAILED DESCRIPTION - The apparatus comprises an optical device, a graphite oxide layer formed on a surface of the optical device, a conveying part for conveying the optical device in a linear motion, and a controller for controlling optical properties and movement of the optical device by the conveying part. The optical device is configured for irradiating light on a substrate. The conveying unit moves horizontally the substrates in a longitudinal direction of the linear motion. The optical device comprises a compact-disk recording apparatus, a DVD recording apparatus, and a blue-ray optical device. The controller controls intensity of light and irradiation time. An INDEPENDENT CLAIM is included for a method for manufacturing graphene.
