Laser levels for civil construction./ Different types of laser levels.

 Now, let us go through some of the FAQs and let us gain a basic understanding of laser levels.

1. What is a laser level?

A laser level is a device that projects a laser beam horizontally and vertically and also a point beam, to enable the person using it to level and align the work that he is doing.

2. What are the different types of laser levels?

Laser levels can be broadly divided into three main types.

They are,

A) 1. Line laser level.

2. Rotary laser level &

3. Plumb, dot, or point laser level.

B) Based on the leveling capability, they are categorized as

1. Manual leveling laser 

2. Self-leveling laser.

C) Based on the beams emitted through laser levels, they are subdivided as

 1. Horizontal beam or single-beam lasers.

 2. Dual-beam or split-beam lasers.

3. What are the applications of laser levels?

Laser levels can be used for indoor and outdoor construction works. Let us check out the indoor & outdoor applications separately.

Indoor applications:

1. To align and fix the flooring tiles.

2. To plumb the walls, doors, windows, etc.

3. For the electrification work, by aligning the switchboards and ceiling fixtures.

4. For fixing the plumbing items like washbasins, sinks, drainpipes, etc. in required levels.

5. To check the height of doors, windows, and walls, easily.

7. In aligning kitchen platforms, cabinets, shelves, etc.

8. For leveling & aligning railing works, drop ceiling works, and many more.

Outdoor applications:

1. For layout and fixing the boundaries of all types of land.

2. For contouring in survey work.

3. For providing slopes of different gradients in infrastructure work.

4. For alignment of infra masonry works.

5. To find out the land elevation.

6. In the estimation of earthwork excavation & filling.

7. To align fence posts and drainage system.

4.  What is the working principle of laser levels?

The laser level projects a beam of light in a vertical & horizontal plane through the amplified diodes. This focused beam of light is reflected through the mirrors or prisms in one direction to work with. These lights are red or green in color for easy working visibility.

 Laser levels that emit beams of lesser width are more precise as the line of level narrows down providing greater accuracy.

5. What is the accuracy of a laser level?

Laser level accuracy usually ranges between ±0.75mm to ±3mm. The accuracy of different types of laser levels is denoted along with the emitted beam length. That means a particular type of laser level is specified by saying that it has an accuracy of ±1/16 of an inch for 100ft. The higher-end models are more accurate & vice versa.
