Abstract: A system for inspecting thin glass includes: a housing including a body and a cover; a first shuttle which fixes an edge portion of the thin glass and reciprocates in a first axis direction; a first inspection part disposed on the body and which measures a position of a defect formed in the thin glass by taking a picture of the thin glass; a transport shuttle which separates the thin glass from the first shuttle, a second shuttle which separates the thin glass from the transport shuttle, fixes the thin glass, and reciprocates the upper surface of the body; and a second inspection part disposed on the body and spaced apart from the first inspection part and which inspects the position of the defect by taking an enlarged picture of the position of the defect. The first shuttle tensions and fixes the thin glass.
