What color laser is the strongest
Since green is the brightest, it does not necessarily mean that it has the best burning ability. Specifically, it is mW (milliwatts) rather than color that determines the combustion and heat ratings of any particular Laser pointer pointer. Therefore, blue lasers of 445 nm and usually over 1,000 mW are most suitable for combustion today. Provides high thermal index and good visibility. This will result in a quick prompt. If someone says "this 1 watt laser is harmful to 25.5 nautical miles," you can immediately calculate that the visual hazard of flash blindness and glare will be within the top 10% (2.5 NM), while the remaining hazard distance (23 NM) is impressive Heart: This 10/90 rule applies to any type of visible laser visual interference hazard (not the hazard of eye injury).
At the federal level, this does not mean that possession of current laser pointers is illegal. It will allow the federal government to prohibit the manufacture, import or sale of new non-red laser pointers. If certain industries require special guidance, the manufacturer can ask the FDA to make changes to allow sales to law enforcement officials or other authorized users. However, the FDA has not yet set a distinction that allows individual sales. Therefore, people who want to buy a non-red laser engraverpointer will not be able to obtain a newly manufactured laser pointer.
For continuous wave (cw), the output power of these lasers is 1 mW or less. Class 2M lasers are similar to Class 2 lasers, but cannot be seen with optical instruments. Generally, these lasers have larger diameters or larger divergence, which is unsafe if used with lenses that can refocus energy. If you operate carefully within the limited beam range, the 3R laser pointer or equipment is considered safe. In the visible spectrum, continuous-wavelength lasers are limited to 5 mW at wavelengths between 400 and 700 nm. If you expose your eyes directly, Class 3B laser is very dangerous, but diffuse reflection is harmless. Class 3B continuous wave lasers in the visible spectrum are limited to 500 mW. Class 4 lasers are the highest and most dangerous types of lasers. ANSI guidelines recommend that the use of Class 3R lasers in situations involving the public should be carried out under the supervision of trained operators, or used in a way that direct or specular reflection is impossible. ANSI guidelines recommend that Class 3R lasers should require safety and training programs. Obviously, these conditions cannot be met when blue laser pointer pointers are sold to the public without any training or supervision.
The documents submitted by TEPRSSC are the first step in formulating rules. Based on TEPRSSC’s response-and most of the members who commented on it-the FDA will then decide on the final proposal, which will be printed in the Federal Register. There will be a period of public comment. According to the comments, the FDA can: 1) retain or slightly modify its proposal and make it a new rule, 2) it can substantively modify it and resubmit it as a new proposal, or 3) it can delete the proposal without making any changes to comply Regulations for laser pointers.
