635nm red laser pointer
Since the wavelength of the laser module produces red, the structure is the simplest, basically just made of a battery-powered diode. 5000mw laser pointers have different colors, different material costs and technical cost prices. Even if the performance is the same. Like 2 catties of watermelon, a variety of yellow and red meat watermelon, the price of meat watermelon. Even if the color is the same and the laser power is the same, the price will be different because of the different styles, material grades, and workmanship. The 1mW Class II blue laser pointer will not cause damage to human eyes or skin. Beam or point. The recommendation of this 635nm high power laser pointer is less obvious than the green laser, and is sufficient for formal demonstrations in school education, star positioning, and astronomical research.This is a good purchase because I did not chew and break it. cheap! Light! Even in a bright room, I can see enough red dots. I bought it because my husband and wife work together and I cannot go for a walk every day. The special emission of the 635nm red laser beam will bring a completely different experience when guiding this red laser in the dark. The 1mW series red laser pointer can project the purest red light under various conditions. This low-power red laser pointer is not as sensitive to the human eye as the green laser, and it is enough to display stars, constellations, astronomical research, bird discovery, school education, exhibitions, etc. People will never regret owning this 1mW red laser pointer on any presentation occasion.

With a permanent power output of 1mW, you don't have to worry about school education, university lectures, exhibitions, lectures, and astronomy. You do not 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-type laser device, don't give it to the bad guys or overuse it. The red laser module first appeared in the 1980s. It is a huge device worth hundreds of dollars. It is now small and cheap. In recent years, a diode-pumped solid-state laser (DPSS) red laser pointer with a wavelength of 671nm has appeared. Although this wavelength can be obtained with inexpensive diodes, DPSS technology can produce higher-quality, narrower-band lasers.You can see the green laser pointer beam. On the other hand, when the air is clear, it is difficult to see the light outside. However, in days when the fog or air is not very clear, you can clearly see the repulsive force of the laser pointer crow, and you cannot judge how far it has expanded.
