How does laser level works?


Rotary Laser Level Tool For Grading

The principle of a laser level is to emit a straight laser line through a laser, with different wavelengths divided into different colors of laser, usually using more green light. Compared to red light, it is much more cost-effective, but when outdoors, green light is easier to see and adapt to.

Internal principle of laser level tool

Laser emitter: A laser beam is emitted through an internal laser diode, and this laser beam has the characteristics of thin and precise lines.

Mirror or prism system: This system will receive a laser beam and scan it horizontally or vertically by rotating it. Therefore, a horizontal vertical line is formed.

Measurement and calibration: By rotating the system in the previous step, stroke a straight reference line in the surrounding environment. Users can adjust or calibrate the horizontal or vertical lines and positions of the workplace as needed by using reference lines.

Extended laser measurement: For some outdoor or large-scale projects, a receiver can also be used. The main function of the receiver is to receive the laser beam emitted by the laser level, and when outdoors, it can clearly display the precise position of the reference line. Therefore, it can appropriately extend the distance of the laser line.

When choosing a machine, you can consider the following aspects:

Customize your own laser level 

Accuracy: It is an important indicator for measuring the performance of laser level tool. Accuracy means more reliable measurement results.

Measurement range: Choosing different measurement ranges for different work requirements can efficiently and affordably carry out work.

Visibility: The choice of light source also determines whether the display of laser lines is thin and stable in different environments. It determines the error of the measurement results.

Function: Different working environments require different functions, such as horizontal tangent, floor tiling, wall tiling, etc.
