What is the irradiation point of the laser pointer
The irradiation point of the high powered laser pointer depends not only on the output and apparent brightness of the laser reflected from the surface, but also on the color version of the human eye. For example, the human eye is most sensitive to wavelengths in the visible spectrum from 520 nm to 570 nm, but less sensitive to red and blue laser wavelengths. Therefore, the 532 nm green laser is brighter than other color lasers with the same output power. The wavelengths of the red laser are 635 nm and 650 nm, and the wavelengths of the green laser are 515 nm, 520 nm and 532 nm. Lasers of different wavelengths will produce laser beams and spots of different colors during operation. A red laser with a certain output power has a better combustion power than a green laser.

Different laser characteristics make the red laser beam less visible than the green laser beam of the same power. The green laser can achieve brighter and clearer green laser beam emission. Users can only judge the quality of the laser pointer based on their exact requirements and personal preferences. Someone may use the green laser pointer for more than 2 years without any problems. However, the recommended laser pointer may also burn out in a short period of time. In addition to the problem of the laser pointer itself, the correct operation of this small laser tool is also very important. The formal operation of the green laser pointer may stop working. Before you need the laser manufacturer to repair, we may check the following reasons: the laser pointer is not operating properly. Long-term continuous pointing of the laser pointer will cause severe high temperature and temperature rise in the laser tube.
