Green laser pointers were once used as a pointer during lectures and classroom discussions, surveying a building, and all kinds of cases where a highly noticeable pointer or a long pointer is needed. Astronomers, both professionals and amateurs, also use this same equipment due to its high visibility at night that helps them in their investigations. This has a lot of practical use for professionals and has been a fad for young people.
There are different colors and different power outputs for laser pointers, but nevertheless, the green laser pointer can appear the most vivid color because it is the brightest color in the light spectrum of the human eye. This 532nm pointer performs even better in the dark and has a continuous beam that travels a distance of 80 miles (wow!). This is not only fun to use at parties and other celebrations but can also aid in SAR (search and rescue) operation, imagine yourself lost in a jungle or sea without light, the green laser pointers can be easily seen for miles Because of their incredible 80-mile visibility, these lasers can also start small fires and some rechargeable models, which just means long battery life.
Therefore, it should be noted that a green laser pointer emits a relative amount of infrared radiation, but the best products have a built-in filter. Some manufacturers of cheaper models don’t want the extra outlay in making the filters, so they don’t stock them. I would recommend that you pay a little more and get one with a filter, for the sake of your own eyesight and anyone else’s.
As with anything you buy, do your homework and check the price range. There is a lot of variation in prices and product excellence, so it is best to look at all the products available, or as many as you can, and decide what would give you good value for money.
