We used the most in life is to all kindsof artificial material, we use the different performance, features outstandingmaterial finished too many problems. Laser protective goggles believes that theuse of laser is absolutely occupied much of share, everyone for the laser imageis usually an omnipotent, but we should also know laser with human body contactcan easily destroy our body, but not direct contact with the laser in our bodywill also because of radiation damage to us. Today, we said to you about laservisible and invisible characteristics.
The laser can be visible and invisiblelaser. The difference between the visible and invisible laser is the key towhether the band in the visible range. Medical and cutting with laser in orderto have high thermal effect, will certainly to high thermal efficiency of farinfrared ray, as the light source so it is not visible laser. And laserintensity is high, as we all know the sun is common to the human natural light,brightness 300000 times larger than the candle on the surface of the sun isbigger than incandescent bulbs hundreds, the emergence of laser, but also atremendous leap on the lighting source. An ordinary laser output intensity, thebrightness of the surface of 1 billion times more massive than the sun,reflected from the earth to the moon in also won't be a problem. Visible laseris high brightness of the light source in the world today.
We in this introduction to the brightnessof the laser, there is a clear understanding of the laser protective goggles tosay the sun is we can't look straight, and the visibility of the laser, if wereally can see visible laser, so our eyes will be blind, the laser burn of eyedisease is irreversible.
