You can buy a Laser pointer arrow at the city conference, you can say there are different laser colors, a big exhibition style. -What kind of laser is that? If you don’t know what science and technology are, or what they are used for, it may be difficult for you to know which lasers are worth buying (maybe frustrating). If you want to know what you have done with laser marking, who you are using, and more importantly, the question of using laser, you are right. Here, we will study different types of lasers, radioactive colors, and light sources so that they can better understand which lasers are emitted to meet their needs.
The visible cursor usually ranges from 405 nm (purple) to 650 nm (red). What is the ood signal of these spectrums from the bottom of the spectrum (ultraviolet) to the visible color (such as green) to the top of the spectrum (infrared)? Ultraviolet and infrared are invisible to unarmed eyes. This kind of long-term radiation is not suitable for ordinary users. Therefore, under the same primitive dynamics, the brightness of the green laser is 5 to 7 times that of other colors. Therefore, the power of 52,000 nanometers in green is 7 times that of 200 megawatts and 7 times that of red or blue.
The laser is the hero of the hand. It can emit more than one powerful light and emit a reflected signal at a specific wavelength. Most of the manual operations you see are performed within the visible range of the brightest green eye at 532nm. In other words, a laser beam means that the finger is on the hand, or “illuminates” it. The available colors are different, the sizes are different, and the colors and properties of the light are different.
