Do you know how to use the engraving laser pointer?

The engraving laser pointer uses a green laser beam because it is well known that these lasers are the most powerful and accurate, with long-distance visibility. Just because green is very close to the center of the color spectrum, it is easier to see by the human eye than other tones that are part of the spectrum, so this type of laser beam can be more clearly visible than red or blue lasers, and more sensitive than them Much. The most important thing about the brightest light emitted by a laser pointer is its applicability in various places. The light indicator can be used not only for presentations in dark rooms, but also in classrooms during the day and the light beam is clearly visible. The green laser pointer is more powerful than the red laser pointer, at least 60 times brighter or more. Therefore, they are visible during the day and from a distance, which makes them more sought after by people. In complete darkness, the range of the green laser pointer can reach about 12,000 feet! For people with pure power, especially young people aspire to have one.
