In wireless technology, remote red laser pointer products usually include infrared and radio frequency. We believe that we are familiar with the TV remote control, air conditioning remote control, infrared technology and other infrared products. Infrared products are directional and transceivers must be aligned with no intermediate obstacles. Rf directional products can be used as long as there is no large metal barrier between the transmitter and receiver. Rf products usually cost more, but are more comprehensive and easier to use. At present, Hainuo electronics has added a full line of products to replace rf technology, infrared technology will gradually fade out of history.

Germany does not ban 3w laser pointer above 1MW, but the European Union has import restrictions. So if there are any problems, they are most likely to happen on the border with the EU. But a word of warning: not only is private ownership illegal, lasers are not toys. If they could light up a piece of paper, they could do something similar to the retina, destroying visual cells, but with enough energy. In this sense, even diffuse scattered light is enough to harm the eye. Suppose a 100mW laser shining on a white sheet of paper damages the retina.

The risk is close to zero, so don't worry. The Green laser diode is almost harmless to the eye and has a power of 5mW. The so-called laser pointer is a display that uses a laser as a demonstration tool. It can replace the pointer display tool for longer distances and can also be used for powerpoint slides, as shown in the picture. The laser pointer is like a straight-through type, but also can control up and down black PPT or Word documents, playing speed. Laser Pointers on the market are mainly red and green. Due to the limitation of technology and cost, blue, yellow and small, when using the laser pointer, you can see the common position within dozens of meters indicated by the laser pointer.
