Laser Levels

The laser level is a level meter that guides the laser beam emitted by the laser device into the telescope tube of the level and emits it along the collimation axis.
ATO offers 2-line, 3-line, 5-line, 8-line, 12-line, and 18-line green laser levels for chosen. The laser level has the advantages of high accuracy, long line of sight and automatic reading. So the high-precision green light level can be widely used in metallurgical steel plate cutting, stone cutting, wood cutting, machine vision, and other fields.

What is a laser level?

In surveying and construction, a laser level is a control tool consisting of a rotating laser beam projector that can be affixed to a tripod. The tool is leveled according to the accuracy of the device and projects a fixed red or green beam in a plane about the horizontal and/or vertical axis.

How does a laser level work?

The laser level projects a green or red beam. The laser is a highly focused and multi-amplified beam of light emitted by the LED diode. Its thickness (the smaller the better) depends on the parameters of the diode and the level of light concentration; an ultra-thin beam enables maximum precision and minimizes the potential error almost to zero, even over long distances of the order of 30-50 meters.

The heart of each laser level is the optoelectronic compensator, stabilized magnetically or pneumatically. Both types perform the same task: they self-level the device, moving within the limit of free movement specified by the manufacturer (usually +/- 3° to 5°). The point is to automatically align the laser beam with respect to the rotational axis for accurate horizontal and vertical alignment. This is only possible if the device is placed horizontally. If the allowable tilt margin is exceeded, many models will signal their inability to level by sound or light signals.

How to choose a laser level?

There are many different laser levels available for use and so there is a lot to consider when trying to choose the right laser level for you. So, what laser level is right for you? Here are some things to consider:

• Accuracy - Laser levels are more accurate than other tools such as the spirit levels.
• Manual vs Auto - Auto lasers, also known as self-leveling lasers, essentially do most of it for you. Once it starts up it will eventually give you a true level line. It will also stop if disturbed, meaning you won't get any inaccuracies. Manual lasers aren't less accurate than auto lasers if they are set up properly. However, unlike auto lasers, if they are disturbed they will carry on running which is why they are better suited to smaller projects.
• Green Beam vs Red Beam - Green beam lasers are easier to see because they appear much brighter. They are only used for large-scale, indoor projects where the line needs to be seen instead of using a laser-level detector.
• Indoor or Outdoor Usage - Are you using your level for indoor or outdoor projects? There are different types of laser levels that could be better suited for it's intended use.
