That’s the thing, they are not true 1 mW lasers. A 5mW ebay laser will meter at 50-120mW. Every laser pen I’ve bought has been over spec
That 405nm from dx will easily……I mean EASILY be 70-120mW. Bith min are 85 and 105 respectively
Btw that 460nm Is a rip off. Dont buy it
Yeah, there are a lot of people doing foolish things with lasers out there. In the U.S., they crack down pretty hard. Check out this.
Lasers have to be handled rather differently (safely) as compared to flashlights. Unfortunately, a considerable number who know how to buy one also point them at people and aircraft. It’s like having a sharpened walking stick; safe if used at home or pointed downwards when walking outside but not when waved around wildly in a crowd outside. Several Nordic countries have already written to the European Commission to clamp down on lasers : HERE
I merely use laser pointer, but I can only accept low powered laser less than 5mW.
It is seriously dangerous once pointed at eyes. I learnt a lot of safety information from wikipedia. Laser safety is really very important.
Never try to point a high power laser unless you have totally understanding safety information of lasers. I am reading laser safety knowledge online.
Wikipedia is never a source of safety information. I could go on there and edit the whole page to say lasers are safe to point at eyes etc……wikis are a joke for actual knowledge, good for getting a general idea on a subject
How can 1mW laser pointer reach high power of 50-120mW? That’s horrible.
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.

I bet you its either a 445nm mislabeled or a Osram PL450B that is labeled at the max of the spectrum.
1mW blue laser seems quite unusual and is safe to use. I know less about 488nm laser. I will find some pics on google image of this special laser.
This 1mW blue laser pointer is very speical and safe to use. I am quite interested in the beam color of 488nm laser. Is it near blue?
Yes, it is a very nice blue-green turquoise color 
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.
On the one that did 240mW of 532nm, how many mW did you measure including IR? You say the rest was IR, surely not the rest of 1W?
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.
I am quite interested in blue color laser pointers, such as 460nm, 488nm laser.
Can you show me the real color of 488nm blue laser light?
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.
