Science fiction often predicts the actual invention of technology.
For example, in 1870, the submarine 20,000 alliance was written, when the submarine was in a highly experimental stage and was not successful at all. Long before the first manned space flight, the story about the rocket entering space appeared.
In this way, before the first laser beam was discovered in 1960, the dangerous and mysterious beam was well known in the novel.
Star Trek was quickly used with beams and ray guns in 1966, but the idea dates back to Tolstoy in 1920s, Verne in 1896, and HG Wells in 1898.
The laser used in the weapon is said to be still in the experimental stage, but for quite some time, the laser has completely changed the construction industry.
The laser is the first letter acronym word amplified by the radiation excitation Emission Light.
It is believed that "oscillation" is more correct than "amplification. . . . . . . . .
But who wants to use the word loser?
It is believed that this ray is potentially dangerous when the laser is first developed.
In fact, even low-power lasers are harmful to vision.
The laser usually uses a number to mark the potential hazard level it may have.
The laser used in the CD player is considered safe because it is closed. [
This is type l/1.
A laser indicator up to 1mw is considered safe as normal blink reflections protect the eyes. [
This is type ll/2.
Lasers up to 5mw have a slight risk to the eye.
Don't stare at this beam. [
This is type llla/3R.
The Lllb/3B laser will damage the eyes immediately.
The LV/4 type laser is dangerous and can cause damage to the eyes and skin.
For industrial and scientific applications.
Protect the eyes when the laser is used for cutting-
Gloves should be worn.
This is often unnecessary for pointers and construction of laser beams.
Look at most "pre-
You will see very amazing irregularities on walls, corners, tiles and even wood products.
This is because builders and craftsmen rely on short-lived spiritual levels, plumb lines and their own "eyes" judgment.
The accuracy of the building is almost guaranteed today. To start with.
There is a simple hand-held laser with a mental level that can block the surface and emit a beam of light.
Even these have a huge impact on accuracy and routing.
But today, a variety of laser tools have been developed.
These provide builders with reference lines that are essential to absolute accuracy.
A wide variety of different types means that each app has a laser tool.
Most of the latest technology tools are automatic leveling.
Some suitable for indoor use;
Others have clearly visible lasers for outdoor use.
Some are useful for short distances while others cover longer distances.
When set at one point, there are even some that have lasers in multiple directions.
This ensures that the angle relative to each other is correctly marked.
