A line laser is a device that uses a laser and optical lenses to project a laser beam as a line rather than a point. It is often used in dimensional measurements to provide a reference line for measuring the size of an object.

The principle of the line laser is the refraction of light. By using optical components such as cylindrical lenses or Powell lenses, and adjusting the geometric shape and optical parameters of the components, the point spot can be converted into a line spot.

When it comes to dimensional measurement, line lasers offer several advantages over traditional measuring tools:

  1. Accuracy: Laser line distance measurement is accurate and reliable, providing precise measurements on a variety of surfaces. Laser measurement tools can be more accurate over a wider range than other measuring devices.
  2. High efficiency: Line laser levels are more efficient than traditional levels. A laser level uses a laser beam to create consistent chalk lines, so it’s easier to get something straight and level. Laser-guided measurement tools provide accurate measurements that are fast and easy to use.
  3. Easy to use: Line laser levels are easier to use and more space-saving than other types of laser levels. Laser measurement tools can be used without an assistant, making them more convenient to use.
  4. Versatility: Line laser levels allow you to lay out reference lines on any surface. Laser measurement tools can be used in a variety of environments, including underwater.

Line lasers are widely used in machine vision, three-dimensional reconstruction, precision measurement, photolithography, laser manufacturing and other fields. It can be used to scan, detect and identify the shape and surface defects of target objects, and can also be used for high-precision measurement and positioning. In addition, line lasers can also be used in photolithography, photocutting and other processes in laser manufacturing to achieve high-precision processing and manufacturing.
