When I sought the pleasure of Laser pointer demonstration, in addition to using the official green laser equipment, I just found that the 5mW blue laser pointer is a very good choice. Its brightness is not as good as 532nm or 473nm laser equipment, but it projects a very attractive blue laser beam and blue dots in the beam aperture. I am very happy to use this laser device for point demonstration. As long as it is easily inserted with two alkaline battery power sources at any time, it can effectively make the most wonderful and wonderful point expression in a variety of work situations.
The primary colors of the laser engraver , green and blue. The other colors we see are produced by mixing primary colors in different proportions. For example, this is how televisions and visual displays work. If you look at a screen with a magnifying glass, you will see that only these three colors are used. For example, red and green are used to make the brain perceive points as yellow.
Suppose you want to transmit magenta, it can be achieved by combining red and blue in a certain ratio. This ability to combine colors has been used to produce the 16 million colors known today.
The indicator chooses a 450nm blue blue laser pointer diode as its beam source. When the blue laser beam is generated directly from the laser beam aperture, it can always work with a more stable point positioning, even longer than the formal laser pointer device. In the actual laser spot aiming work, it can work within 30 seconds, and the laser dim or fuzzy appearance will not appear in the continuous pointing work.
Birds living in groups with many other birds and their families have a collective defense mechanism. If you ever find Canadian geese grazing by a pond, there will always be at least one goose that has no direct access to the food source, but in fact it has been scanning the area. They are safety nets and will warn the entire flock if they need to escape suddenly. When they are frightened, they will remind all the sheep to run away and they will all fly into the air. A high-power green laser is a great way to get an alert and send it into the air. It is for this reason that homeowners, airlines and airports use these laser tools. In order to keep the airport’s runway and surrounding routes as far away as possible from poultry, and to allow homeowners to prevent their yard from being soiled.
