The status quo of green laser pointers
Among all laser product lines, the green laser pointer is considered the most practical and popular laser. In the past, the green laser pointer was only used in our daily life, and was only used as a presentation tool in teaching, lectures, speeches, business meetings, conferences and other occasions. The 5mW green laser pointer has always been an ideal choice for such people. Practical use Although higher power green laser pointers ranging from 100 mW to 150 mW are usually great for finding entertainment. For example, a 100mW green laser pointer with an infrared filter is sufficient to burst balloons, light games, light matches and burn plastic, melt rubber, and cut electrical tape. The 100mW green laser pointer is so powerful and bright that you can only light a cigarette once in a few seconds. However, professionals are never satisfied with the results achieved. On the other hand, they begin to focus on exploring more and more practical applications of green laser pointers in our daily lives.

Application
The green Laser pointer is often used in teaching. It is a modern teaching mold and equipment. The teaching laser pointer is the third generation of writable laser pointers. Teachers, trainers, and lecturers all touch when making teaching demonstrations and project demonstrations. To this kind of embarrassment, it is necessary to explain while operating the computer, and the movement is restricted, which is very inconvenient. How to completely liberate users during teaching demonstrations, and truly realize "where to go, where to talk, where to talk, and where to point". The emergence of laser pointers really solved these problems and freed the speakers completely. For astronomy enthusiasts, how much power and price should be chosen to meet the requirements of pointing stars? I personally think that the power of 20mW to 50mW is more appropriate, and the power of 50mW or more can already feel particularly dazzling under dim indoor conditions. The price of a laser pointer is mainly related to its bandwidth and stability. The narrower the bandwidth, the more expensive the price, but the human eye can’t tell the difference in bandwidth at all. Therefore, friends who are more economically struggling choose the power below 50mW, and the price is A laser pointer below 100 yuan is more suitable. In addition, the power consumption of the laser pointer is generally relatively large. Based on the principle of environmental protection and saving, it is also necessary to have a good pair of rechargeable batteries. The current price of 50mW power is not very expensive, only a little over 100.
