Laser products can be a single laser with independent power supply or independent power supply, or a complex optical, electrical or mechanical system with one or more laser. Laser products are generally used for demonstrations of physical and optical phenomena, material processing, data reading and storage, information transmission and display, and so on.
These systems have been used in industry, commerce, entertainment, research, education and medicine. However, the sale of laser products for other manufacturers as any system component may not comply with this standard, because the final product itself must obey this standard.
Thermal effect is the main cause of laser radiation damage, but for laser radiation of specific wavelengths, we also need to consider optical hazards.
Application standard IEC/EN 60825-1
Regulations for laser classification:
Class 1 laser product
During the work period, during the corresponding wavelength and launch duration, the laser radiation of personnel contact does not allow more than 1 category to reach the laser product that can reach the launch limit (AEL).
1M laser product product
In the wavelength range of 302.5nm ~ 4000nm, during the work period, during the corresponding wavelength and launch duration, personnel contact can reach laser products with laser radiation that can reach more than 1 category.
2 types of laser products
In the wavelength range of 400nm ~ 700nm, during the work period, during the corresponding wavelength and launch duration, personnel contact can reach laser products with laser radiation that can not be allowed to reach the laser limit (AEL).
2M laser product
In the wavelength range of 400nm ~ 700nm, during the work period, during the corresponding wavelength and launch duration, personnel contact can reach laser products with laser radiation that can not be allowed to reach the laser limit (AEL).
3R and 3B laser products
During the work period, personnel contact laser radiation allow more than 1 and 2 categories to reach the launch limit (AEL), but at any launch duration and wavelength, personnel contact with laser radiation does not allow more than 3R and 3B to reach the launch limit ( AEL) laser products.
4 category laser products
Personnel contact laser radiation allows more than 3B of laser products that can reach the laser limit (AEL).
