Blue violet laser pointer- compactness, reliability and effectiveness

The blue violet laser pointer is not very much different from the other lasers which produce beam of any other color. Actually, the main thing which makes them different is the length of the wave. People who were careful enough in physics classes probably remember that it is the light wave's length that determines the color of the light. For example, if a laser pointer produces beam with light wave's length around 400 nanometers it would be violet laser pointer. And if the laser pointer pen produces light waves with length of around 700 nanometers, the color would be red.

Anyway, it could be claimed that the blue violet laser pointer and the purple laser pointer can provide better effectiveness in particular situations. For instance, violet, blue and purple are considered to be brighter colors which would be seen more easily in the dark. So there should be no surprise that the blue violet laser pointer and the purple one (they are almost identical by the way) are often preferred by climber and mountaineers. They need laser pointers so as to use them to give SOS if they get lost. Logically, they prefer the lasers producing light beam which is more likely to be seen. Furthermore, the violet lasers have a huge range which can reach 10 kilometers.

But the blue or purple laser pointers are not used only because they have a good range and are more visible in the dark. Users also tend to like them because of their compactness and reliability. Unsurprisingly, the compactness is owed to the small size (around 15 cm long and approximately 5cm wide), which makes the laser portable and easy-to-carry even on long trips and expeditions. And the reliability is owed to the high-quality batteries which the blue violet laser pointer has got. They are actually not rechargeable but replaceable AAA batteries which can be bought from every shop. But as the device is power saving, 2 AAA batteries are usually more than enough to provide several years of usage. And that makes it quite a reliable gadget also because it will certainly function and work properly when it is needed the most, unlike most of the other gadgets.
