How can a chinese company list a flashlight as 1200 lumen and it only do 400 lumen? Its china they don’t follow any rules. They are not FDA approved so they can’t legally sell them in the USA. Hoe do they get around the law; label them as under 5mW, that’s how. They are not really 5mW or 1mW in your case, but that’s what they say so that’s what buyers believe. Its the biggest problem with lasers. People think they are safe and point them at humans or aircrafts and then the rest of us laser enthusiast get a bad rep and more laws placed on us.
Don’t fall into the trap and become a laser idiot. Visit laserpointerforums.com and educate yourself on lasers……please for the sake of the rest of us and for everyone’s safety.
Have you already bought this laser pointer? Do you own it now? Yes 460nm is a unusual wavelength for a laser, usually only available in OPSL (optically pumped semiconductor laser) or possibly DPSS. Yes the coherence & purity of laser light is beautiful to look at. 460 is a very nice color. My personal favorite is 488nm (an argon line) bluish-green or cyan) .
You were indeed wise to start with a class II 1 mw laser (hopefully it is that, and not too over powered, although up to 5mw is considered low power too. You seem to be aware of the inherent dangers of laser light, so that is a very good start. We usually recommend laser safety goggles (most are wavelength specific) but in your case it would block most of the light. Just remember never point it at any living being , including those in vehicles, aircraft etc. Enjoy your laser!
As far as the reputaton of the seller, I’ve had no experience with them, so I cant comment about that.
Regards,
Most of it is IR radiation, not visible light. I measured couple of Chinese 1000mW laser pointers and most powerful had 240 mW pure green, rest of it is very dangerous IR radiation - those laser pointers don’t have IR filters.
most of laser pointers are not designed with IR filter. For instance, there might be tiny red light emitting from a high power green laser pointer. High power laser is not recommended.
although IR laser is invisible to eyes, however, it is extremely dangerous to naked eyes. High power lasers are obviously not wonderful choice for use.
Yeah you can buy whats you want. The point is whats you do with it. I have got a 1000mW green laser easily and no law I found for limits for that high power laser. Actually it’s easy to break that laws if they exist.
I can only bear low powered laser pointers range in Class IIIA. I am interested in both 1mW or 5mW green/blue laser pointers. They are using safe and being available at low price.
It is not safe to point high powered laser gadget to yourself and people around. There might be potential dangers to operate a powerful laser. Do be cautious and enjoy laser fun freely.
Above, ordinary LEDs; then when you intensify that by what a laser emits:
