Are there any precautions for buying and selling laser pointers?
Laser pointer can only be placed on the market under the following conditions. They are classified (according to DIN EN 60825-1) and correspond to laser class 1, 1M, 2 or 2M. The laser category must be marked on the laser. Lasers are designed in such a way that their radiation is provided in a very clear beam.Send out a very small divergence. This option is used with the laser pointer. With relatively small power, you can see the screen farther away, with a clearly visible light spot instead of the pointer. The technology implementation is based on a diode laser with a wavelength range of 630 ÷ 680 nm, (red) or a diode-pumped, frequency-doubled solid-state laser with a wavelength range of 523 ÷ 537 nm (green). Both types can be powered by standard batteries. Sometimes, there is a CE mark on the laser pointer. However, this does not prove that the laser pointer is correctly classified, and the maximum output power is 1 mW observed. The GS mark affixed to the product means safety testing and certification, and an approved testing and certification organization has been established.

It is recommended to be cautious when buying and selling laser pointers, especially cheap products, because GS mark forgery is often found here. Every consumer can submit unsafe products to the responsible market surveillance agency. Once the government determines in its regulatory activities that the laser pointer does not meet the above requirements and those that comply with relevant regulations will be prohibited from distributing or selling laser pointers. If necessary, the laser pointer was also ordered to be destroyed.
