Hands-free laser pointer pocket and compact life essential
This class IV laser has the strongest power of a high powered laser pointer in the beam, exceeding 500 mW, and can cause serious and permanent damage to the eyes and skin without being optically amplified by the eyes or instruments. I have. If you want to burn the laser, you need goggles. this is very important. Short-range laser radiation damage is the corresponding long-range damage. If the lasers have the same parallelism, high-power lasers of different wavelengths have different focal lengths. For example, the focal length limit of the 1064 nm infrared laser is 20 times the focal length limit of the 532 nm green laser. In other words, the intensity per unit area of the 532 nm green laser is 20 times stronger than the 1064 nm infrared laser with the same output power. Generally speaking, long-wavelength lasers have a larger focal length than low-power lasers.

Application
The recommended green laser pointer has the characteristics of high brightness and high visibility, and is widely used in military, astronomy, scientific research and other fields. Traditionally, red laser pointers have been used for presentations in business meetings, conferences, conferences, speeches, etc. The powerful beam is very helpful for the speaker to observe this clearly. However, in military and astronomy, the demonstration function plays a bigger role. If you are a super laser enthusiast or have research needs or other special purposes, you want to buy a high-power blue laser pointer that does not meet the low-power green-red laser pointer. The problem is that there is no uniform price for high-power blue laser pointers in the market. And many companies use low-power blue light as high-power to fool consumers.
