Ordinary consumers can contact or use products, such as high power laser pointer, laser measuring equipment, tools with laser instructions, generally not higher than 3R class. Some markets, such as Europe and Australia, require indicating lasers, such as laser Pointers, to meet a level 2 or lower requirement before they can be sold. Class IV control measures include viable closed beam paths, establishment of controlled channel areas for trained personnel only, issuance of warning signs, operator training and medical testing, and use of standards. Class II laser products have an output power of 1 milliwatt. It won't burn your skin or cause a fire. This type of laser is not considered a dangerous optical device because eye reflection can prevent some eye damage.
When using class 3B and above laser, workers should remove any shiny surface objects such as decorations, watches, badges, etc., from the body. And wear protective glasses to prevent reflected light from entering the eyes and causing damage. Long hair tied up, lab cap on. If you use laser cutting equipment to process dust-prone materials, wear a dust mask to prevent fire.
CLASSII laser is also a low energy laser (power Lassiia laser is a continuous laser wave, belongs to a medium energy emitting device (1-5 milliwatts)). Examples of classiia and CLASSII lasers are roughly the same, such as laser Pointers, laser scanners, etc. Looking at a classical laser is very dangerous. Under no circumstances should you look directly at the Calssiia laser. Do not aim the Classiia laser pointer at anyone's eyes. Viewing classical lasers through binoculars is prohibited. These are the questions we must pay attention to.
