Finished the rough plumbs and the partitions not straight, thanks to the laser level. Very easy to use, the laser level has many practical features for the handyman. Here’s how to use it.
The tools needed
- a laser level;
- a pencil or a line;
- a tripod or a cane.
How does a laser level work?
In appearance, nothing seems to differentiate the laser level from a spirit level. In presence, only since this tool widely used by professionals has a pointer that emits a beam of red light that allows the handyman to obtain accurate measurements. Depending on the model, the range of the beam varies between 15 to 100 meters for outdoor lasers. There are advanced lasers such as rotating lasers or automatic lasers with a tripod. It is strongly recommended to invest in a model integrating an automatic upgrade.
The steps of use
- Position your laser level on the floor using your tripod or cane to stabilize it.
- Point the beam at the opposite wall. Set the height approximately. The level indicates the precise point of arrival of your partition. Adjust if necessary to find the desired level. Position your level as close as possible to the area you are working on. This will guarantee you a flawless accuracy.
- Trace your marks with a pencil or chalk, so you do not have to repeat the adjustment if the laser level is moved.
- Avoid looking at the light beam of your laser level in front. On the other hand, there is no risk if your skin is in contact with the beam.
Applications of laser radiation
After the invention of the first laser in the sixties of the last century, it was not entirely clear what the new invention should be suitable for. ” The laser is a solution in the search for a problem ” was written in the trade press, but now it is easy to lose track of the many different laser applications.
In the following, some application areas are presented and some further links are given.
field of use
Laser for the removal of tumor tissue (laser-induced thermotherapy); with the help of optical fibers, the radiation is led directly to the tumor.
Laser for attaching a detaching retina. In the vicinity of the detachment, scars are created with the laser, which causes the retina to reconnect to the substrate after some time.
Vaccination of varicose veins: A thin laser fiber is pushed into the vein with a catheter. With short laser pulses, the vein is thermally damaged, the vein walls contract. Finally, it comes to venous occlusion.
The laser delivers the directional beam so that straight tunneling is possible at the tunnel.
Mass spectrometry (a laser is used to excite the higher atomic or molecular states).
Examination of the atmosphere (LIDAR: light detection and ranging ). The backscattering of the laser light by particles in the atmosphere can be used, for example, to remove clouds and the like. Determine.
Drill, To cut, welding.
With high-power lasers, very dense plasmas of high particle density and temperature (~ 1 million degrees) can be generated.
