We recommend this laser pointer
The number is sent via wireless technology, so teachers can also send it directly to the presentation. You no longer need to fiddle with the screen. Therefore, it can distract viewers and listeners. The connection with the PC is done through Bluetooth wireless technology and a compatible USB dongle, and it receives the signal from the green 1000mW high powered laser pointer. The green of the brightness laser pointer is more objective, so the eyes are more dangerous, the higher the performance, the more dangerous. Generally speaking, 5mW is widely used, and 5mW laser pointers above 5mW can be used in the market as needed, but special approval is required. We not only pay special attention to the safety of users who are not facing the eyes or other dangerous areas, but there are no strict restrictions to prevent the reflected laser light from entering the eyes.

Let's talk about the maximum power issue. Let's briefly explain the maximum power limit of various colors of laser pointers. The maximum power of blue light will not exceed 5000mw, the maximum power of green will be 1000mw, and the maximum power of red and purple will not exceed 500mw. From this point, the possibility of excessively exaggerating the power of high-power laser pointers in the market can be ruled out, such as 30000mw blue light, 5000mw green light, etc. This is impossible.
