Abstract
The present disclosure relates to a device for calibrating a laser level, including a base platform configured to support the laser level that is to be mounted at a first position of the base platform, a laser detector arranged at a second position of the base platform and configured to receive a laser, and an optical path extension device arranged at a third position between the laser level and the laser detector and configured to receive the laser emitted by the laser level and project the laser to the laser detector after the laser is adjusted by the optical path extension device. With the optical path extension device, a physical distance between the laser level and the laser detector can be optically extended.
