Special astronomical laser pointer
For safety reasons, laser pointers above 5mW are illegal in many countries. But it's important to note that many laser men tend to buy high-powered laser pointers for a cooler experience. Currently on the market are more popular green, blue and red laser pointers. Laser enthusiasts always choose different laser tools to achieve their goals. Different laser pointers and different laser pointers have different outputs. For astronomy enthusiasts, lasers above 50 mW are suitable for observing stars and other celestial objects. As laser pointers developed throughout the astronomical field, experts invented special astronomical lasers. It seems that you can freely manipulate the high power laser pointer beam. I installed a powerful laser diode in the palm of my hand, supposed to be used by club DJs, and made a free-lighting laser glove. And, not only does it glow, it pops balloons, burns trees, and CD cases. In the eyes of humans, the other party is a dangerous object that can cause blindness. The compass is connected to the back cover of the flashlight, the side wall of the flashlight is connected with a laser pointer positioning device, the laser pointer is fixed on the wall of the flashlight through the positioning device, and the end of the laser pointer is connected to the back cover ring of the flashlight through a string.

The red laser pointer is certainly versatile and is often used as a pointing device in business presentations and seminars. Therefore, its principle is very different from other types of lasers. The beams are produced by elementary particle accelerators (similar to those used by physicists to study particles). Electrons are injected into the middle of a series of permanent magnets (inverters) to create a periodic magnetic field. In an inverter, two parallel mirrors reflect the synchrotron radiation emitted by the electron beam and become coherent (hence the properties of laser radiation). Use a green light that looks bright even from a distance. Consideration has been given to improving the visibility of laser light regardless of individual differences in color vision. With the buttons at hand, you can page forward/backward in PowerPoint, perform slideshows, and blank screens. Using RF (radio waves) as the communication method, it can transmit in all directions. Red laser pointers are mainly used indoors and in dark places. The green laser pointer is suitable for outdoor conditions and long-distance use. The compass disc and needle have phosphor. The positioning device is a shell with a socket or an elastic rubber circle hole, and the laser pointer is directly inserted into the shell for clamping or passes through the elastic rubber circle hole for clamping.
