Description of the color of the laser pointer

The first lasers étaient lasers à gas using the hélium (f) à 633 nm (HeNe). The laser pointer, the least expensive is constitutedé diode laser rouge foncé, close to 670 nm / 650 nm. The use of diodes of red and orange à 635 nm is légèsurely supélimit. This is the wavelength most visible to the general public and the colorblind. There is éalso of laser pointers in other colors. The laser that you know well is the pointer green laser powerful à 532 nm.

These lastères années, laser pointers, yellow and orange à 593,5 nm appeared. A blue laser pointer à 473 nm appeared in September 2005, and a blue-violet laser à 405 nm in 2010. Not only the brightnessé of the laser pen déterminée by the output power and the réflectivité of the surface, but the perception of colors by humans is éalso an important cause. For example, how easy is it to l’&connection;it is human to see a green laser à 520-570 nm? The lumière the most sensitive to the connection;it human is the lumière green à 520-570 nm and as the wavelength of red or blue is infélimit à la visibilité humaine, la lumière green is another color of the m&stop, me power output. It is more luminous.

● Red - The first red laser pointer first appeared in 1980, with hundreds of dollars for éfacilities large and heavy. Currently, it can &our vision to be easily producedé à low co&burning;t.
● Yellow laser Pointer, yellow is close to gold. It has a beautiful wave-length of 593,5 nm, is relatively bright and offers a good visibilité. Is it the laser pointer yellow? It is très rare. Because it is a colour rare, it is more chère as green and blue. If utilisé démonstrations, this will cause a careful considérable.
● Green - The green laser pointer is 8 times brighter than red laser pointer. In the evening, you can see the lumière blue the hands to the sky. Fans d’astronomy l’is often used as a comment of constellation at d’astronomical observations and sky étoilé, and take advantage of the beautiful sky étoilé as a point de repère. There are many types of laser pointers green function of the output power. If you buy a laser pointer with high power, you can buy it on the site to online purchase.
●Blue - The blue laser n’is not as bright as the green, but c’is a laser pointer très facile à use it because it éless d’éblouissements.
● Purple - The lumière, ultraviolet is a laser diode blue-violet violet wavelength of 405 nm.The laser à semi-conductor is close to the low visibilité, but can stimulate the action of the bill and to test chemicals, and fluorescence. Très near the end of the UV spectrum.

It is forbidden to illuminate a pointer laser ultra powerful about a person or an animal. If you look directly at the laser with an output power lower, you will be ébloui. Because of the température élevée of the laser pointer high power, m&stop, me indirect illumination may cause damage to the rétine, or cause a éblouissement enough to entered cool ner a éblouissement eyes.

In addition, the green laser pointer astronomy has a protective effect, but this n’is not a éléments protector. The laser pointer high power éputs a lumière green laser and the intensityé lumière blue laser, with a lumière alive à a certain distance (about 10 mètres). (If you &stop;your a big fan of laser pointers, try all the flash effects you-m&stop, me, but be sure to wear laser safety goggles.) If you use a laser pointer to éclairer imméimmediately your connection there, you might be d'&our vision to be confused or confusing, However, in terms of cécité, strength and exposure time, there is a risk of total loss of vision. The powerful laser pointer situé au-above 500 mw produces a thermal effect to a fixed distance. The more the power output is élevée, the greater the thermal effect is powerful.

In the case of 3 à 4 mètres, a laser beam can &stop;tre utilisé for the lighting of matches and cigarettes. In the case of less than 2 mètres, we écornet imméright now. With the focal length, the laser beam can leave the CD in a radius of’a mètre.
