The recommendation of this 635nm red laser pointer is less obvious than the green laser, and it is sufficient for formal demonstrations in school education, star positioning and astronomical research. No need to wear laser protective glasses. In addition, do not point any type of laser pointer at moving vehicles, airplanes or airplanes. There is a huge and sharp laser beam that can dazzle the eyes temporarily. Whenever people point to a pen laser device, don't put it in the wrong hands or overuse it. In astronomical research, people usually have to point, wave their arms, scream loudly, and point to celestial bodies to explain a lot. In this case, it is always difficult for teachers and teachers to tell which celestial body they are referring to. Therefore, the visible super bright green laser pointer is an excellent alternative to traditional pointing tools such as sticks and fingers.
Most people usually want to use telescopes for professional astronomy research. However, astronomers are limited by the position, angle and distance at which they observe the stars and celestial bodies. Due to the weak light emitted by the telescope, it is always annoying when people are restricted in the search process. In this case, astronomers can try to connect the blue laser pointer to the telescope for remote starry sky observation and demonstration. More importantly, the specially equipped laser stand provides a great help for 360-degree rotation to fully observe stars and other celestial bodies. As a newly developed technology, laser engineers have never stopped pursuing an increasingly powerful green laser pointer. Therefore, experts are not limited to primary laser pointers, but have also achieved important results in higher power green Laser Pointer. The current power range of high-power green laser pointers and portable green lasers is from 5mW to 50,000mW.
