A level that uses a laser beam instead of manual reading. Guide the laser beam emitted by the laser into the telescope tube and shoot a horizontal laser beam along the collimation axis.

By utilizing the monochromaticity and coherence of laser, a glass or metal plate with a certain shading pattern, namely a zone plate, can be assembled in front of the telescope objective to generate diffraction interference. After focusing through a telescope, a bright and fine cross shaped or circular laser spot is obtained within the focusing range of the zone plate, thereby more accurately illuminating the target. If equipped with automatic tracking photoelectric receiving targets on the front and rear leveling rulers, leveling measurement can be carried out. In construction surveying and large-scale component assembly, a laser level is commonly used to establish a horizontal plane or line.
The digital level is currently a relatively good level, combined with a specialized barcode level. Through the built-in digital imaging system in the instrument, the barcode reading of the level is automatically obtained, eliminating the need for manual reading. This instrument can greatly reduce the labor intensity of surveying and mapping operations, avoid subjective reading errors caused by human factors, and improve measurement accuracy and efficiency.
