Abstract
A level correction system includes a first adjustment device, a chuck device provided on the first adjustment device, a first reflective device provided on the chuck device, a second adjustment device, a carrying table provided on the second adjustment device, a second reflective device provided on the carrying table, a laser emitter configured to emit incident laser light, a laser receiver, and a controller. The first reflective device and the second reflective device are used to reflect the incident laser light to form a reflected laser light. The laser receiver is used to receive the reflected laser light. The controller is used to determine a height of the chuck device or the carrying table and whether a center point of a reflected light spot formed by the reflected laser light is offset from a center point of an incident light spot formed by the incident laser light.
