How to classify best class 4 laser pointer?

Laser, abbreviated as LASER, or laser, refers to the process and instrument of a narrow frequency optical radiation line that generates a collimated, monochromatic, coherent beam through stimulated radiation amplification and necessary feedback resonance. Basically, generating laser requires three elements: "resonant structure", "gain medium" and "excitation source". In the process of R&D and debugging, we sometimes cannot determine the Laser pointer level of a certain part of the product. At this time, we cannot simply assume that its level is the same as the laser source level or a very low level because of the trouble. On the contrary, we generally want Assuming that it is Class 3B or even Class 4, take adequate safety protection measures, such as wearing laser protective glasses, protective gloves, etc., to avoid accidents.

Laser class:

1. Class I laser products have no biological hazards. Any beam that may be viewed is shielded, and the laser system is interlocked during laser exposure.
2. Class II laser products, the output power is 1 milliwatt. Will not burn the skin, and will not cause a fire. Because eye reflection can prevent some eye damage, this type of laser is not considered a dangerous optical device.
3. Class IIIA laser products The output power is 1mW to 5mW. Will not burn the skin. Under certain conditions, this type of laser can cause blindness and other damage to the eyes.
4. The output power of Class IV laser products is greater than 500 milliwatts. Such laser products must be able to cause eye damage. Just like burning skin and lighting clothing, lasers can ignite other materials.
