Are class 3B laser Pointers dangerous?
In cities, we can see that the two kinds of people, one is a commuter bicycle commuters, who is another kind of outdoor sports enthusiasts, they seek more and more equipment quality, so the requirement for ride a bike is very high, solution company recently launched a set of intelligent red green laser pointer light system, allowing you to ride more secure, more at ease, can control lights show the direction, Will detect the bicycle deceleration, automatic red light display status. To see laser "dots" on walls or surfaces indoors or in dim light, a 5MW green laser pointer will do the job. The most demanding universal pointing applications are pointing at objects in bright sunlight, such as a daytime tour of city buildings, and pointing at stars at night when you need to see a beam of light in mid-air. For these uses, 5-25 mW should be fine, with a maximum of 50 mW for harsh conditions (high ambient brightness, showing stars to a large crowd).

The UV 500mw green high powered laser is most notable for its ability to accomplish all of the above applications in one step. What does this mean for making circuit boards? People no longer need to use the same process on different equipment and methods to achieve an application, only one machining can obtain a complete part. This simplified production scheme helps eliminate quality control problems when switching between boards of different processes. No UV debris ablation also means no post-treatment cleaning is required. Class 3B laser Pointers are dangerous to the eyes. They can heat skin and materials but are not considered a burn hazard. For visible light lasers, the output power of class 3B lasers is between 5 and 499 milliwatts. Class 3B is the same as the Roman numerals "Class IIIb" that you might see on some laser labels.As laser power increases, so does the risk of eye injury. At the high end, around 250 to 500 milliwatts, even brief exposure can cause retinal damage. Avoid exposure to class IIIB laser beams. This includes unintentional or accidental exposure - taking care to keep the beam away from the eyes and face.
