Features of Class 4 laser
Output power
The output power of a class 4 laser is more than 500mW, and the technical requirements are relatively high for this power range. We have focused on high-power laser pointers for more than 20 years, and the maximum power that we can achieve is up to 20W.
Prices
For class 4 laser pointers, we recommend that you choose 445-450nm blue lasers, which are cheaper than those of other wavelengths. Of course, you can also select class 4 green/red/violet/infrared lasers, but their prices will be higher.
Applications
The class 4 laser pointer can be used for cutting, engraving, medical treatment, scientific research, etc. It is also one of the collections of laser enthusiasts.
Precautions
The powerful laser pointer is not a toy. It is dangerous if used improperly. If the output power is more than 2W, the laser beam can burn things quickly. Therefore, when using class 4 lasers, please prevent fire accidents, and we recommend that you wear safety glasses.
