Tips: Working principle of laser level

A laser level is a level that uses a laser beam instead of manual reading. The laser beam emitted by the laser is guided into the telescope tube to emit a horizontal laser beam along the collimation axis. Using the monochromaticity and coherence of the laser, a glass or metal sheet with a certain shading pattern can be assembled in front of the telescope objective lens, that is, a zone plate, to cause diffraction interference. After focusing by the telescope, a bright and fine cross-shaped or circular laser spot is obtained within the focusing range of the zone plate, so as to collimate the target more accurately. Equipped with photoelectric receiving targets that can automatically track on the front and rear leveling rulers, leveling can be carried out. In the construction survey and the assembly of large components, a laser level is often used to establish a horizontal plane or horizontal line.
