During the layout phase, the construction laser is employed to offer a level of reference. The term “laser” stands for Light Amplification by Stimulated Emission of Radiation. In simple terms, the laser emits a beam of light that creates a leveled plane that may be used to measure elevation or grade.

Some lasers may tilt the plane of light to create a slope in one or both axes (single slope) (dual-slope). Some interior lasers can create reference points in the form of points or dots, along with lines to aid in the layout of walls or ceilings. A compensator is built into every laser to ensure that beam is level. The quality of the compensator and how it keeps calibration is the difference between a $500 laser and a $3,000 laser. There are many different kinds of lasers for construction at various price ranges; which one is appropriate for you will depend on the job’s requirements.

Types of construction lasers

1. Spot Laser: Such lasers are used for a reference point on the work surface for example a ceiling or a wall.
2. Line Laser Levels: These lasers will project a single level line in one direction onto a single work area. These lasers are typically used inside and can be installed on a tripod, a wall, or a ceiling.
3. Rotary Laser Levels: These lasers create a 360-degree level line around the entire room. This laser is often larger as compared to a dot and line laser, therefore thus is better suited for interior use. They can, however, be used outside alongside a laser receiver. This laser is commonly fixed or mounted on a tripod. For longer distances, rotary lasers are employed, whereas dot & line lasers can be used for distances under 150 feet.

Things to consider when purchasing a construction laser

When purchasing construction lasers, think about the task you’ll be undertaking. There are a few key features to think about while making a purchase.

1. Self-leveling or manual leveling

If you use a manual leveling laser, you may have to adjust the leveling screws on the bottom to center the level vial manually. A self-leveling or automated laser will automatically find a level within a given range. Some lasers let you use a level vial to get a rough approximation of the level, and afterward, the laser would level itself precisely.

2. Dual-beam lasers or horizontal

A single beam is produced by a horizontal beam laser, but a dual-beam laser also referred to as a split-beam laser, produces vertical and lateral beams to create a regular position. They will also serve as a point of reference.

3. Laser detectors

With rotational laser levels, laser detectors are employed. When utilized outside, the detectors are normally fixed to level rods and also can detect the laser beam. These are required for occupations that require working outside as the line can indeed be difficult to be seen in bright sunlight. When they are near to being level, many detectors will sound an auditory and visual alarm.

4. Fixed rotation speeds or variable rotation

Rotary lasers can have a variable or set RPM (rotations per minute). A higher RPM will travel further and provide more range, but it will also be brighter. It’s easier to notice at a slower RPM, but it won’t move as far.
