People familiar with blue high powered laser Pointers generally have two different attitudes toward laser minions. First, it does not require a laser pointer and is dangerous to the human eye. Laser enthusiasts who hold the second opinion think that laser Pointers are of great help to us, but they are really good helpers in our daily life. Personally, laser Pointers hurt my eyes, but I think they're still a necessary tool for stargazing and long-term demonstrations. As a general rule of thumb, note that lasers below 200mW do not provide enough heat to burn, but lasers above 200mW produce enough heat to be considered a thermal laser. That's important. If you're looking for a laser that can illuminate matches, etc., make sure it's at least 200mW.
Laser widgets are suitable for astronomy education. The teacher simply invokes and points the laser at a particular star or something else. This is somewhat similar to the display function recommended by laser Pointers. Of course, it's very practical and practical. Therefore, astronomical lasers can greatly improve the efficiency of teaching. The green laser pointer is always designed as a pen. In the laser pointer recommendation, select only the air cooling system. In every continuously operating laser age, the laser beam is always very stable and visible. The operation is also very simple and practical. After releasing the back cover, the laser operator simply plugs in two AAA batteries. After inserting the battery in the right direction, the green laser designator will start working and you will see a very bright and clear green laser.
Compared with traditional astronomical observation tools such as single stick, human finger and telescope, people can get a completely different experience from the special astronomical tool - green laser pointer with mini safety lock. In astronomical studies, people usually point, wave their arms, scream, and point at celestial bodies to explain a lot. In such cases, teachers and teachers often have difficulty in making clear which celestial body they are referring to. Thus, the visible ultra-bright green laser pointer is an excellent alternative to traditional pointing tools such as sticks and fingers.
