▎ 摘　　要

NOVELTY - The inspecting apparatus (101) has a light processing unit (110a) that emits at least one light on the graphene board (301) and any received light penetrating the graphene board is converted to an output signal. A transmittance detecting unit (121) then receives the output signal and inspect transmittance of the light penetrating the graphene board. A determination unit (131) coupled to the transmitance detecting unit, receives and analyzes the detected transmitance to determine state of the graphene board. USE - Graphene board inspecting apparatus. ADVANTAGE - Time to inspect the graphene board, particularly graphene boards with large area layers, is reduced by using visible rays and wavelengths and including a beam splitter. Manufacturing time and cost are reduced since error in patterning the graphene board is immediately corrected when detected. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene inspecting method. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of the graphene board inspecting apparatus.
