1. spectral sensitivity of eye to green is higher than red = 1mw green is brighter then 1mw red 2. brighter green beam is wider - in some applications it is worse 3. camera has low dynamic range - it overdims the weaker laser 4. the weaker the laser, the less chance you need surgery to restore eyesight
If his estimations are correct, all of the ones he's showing are completely safe. 5 mW has been tested to produce only completely heal-able damage to the human eye if pointed directly into the eye for something like 1 minute continuously.
So if someone is stood unseen in the distance you damage their eyes ? One doesn't shoot guns without knowing there's no one in the line of fire. Same applies to high power lasers.
nm stands for nanometers, which is how far apart each wave on the laser is... the lower the number the brighter the laser is because the waves will be closer together in the beam and more "dense"..... mW however stands for milliwatt and that is how much power the laser has. two totally different things
For those who never was in shool: MW = megawatts (LOIC) mW = milliwatts (laserpointers) nm = nanometers, wavelenght of that emitted light (~532 = green, ~404 = blue, ~636 = red, 1064 = IR, co2 lasers) what the fuuuuuuu
You're right. I bought a 5mW green laser off ebay and I compared it to my 50mW laser, the 5mW had a much better beam! So I was quite annoyed that I spent more money on a 50mW when I didn't have to so I ended up sending it back lol.
Kyle Warden you cant measure the effect of at laser on its brightness since that has to do with its wavelength, thats why cheap 100 mw lasers are so dangerous because you barely see the beam tough its burning your eyes like hell,
the nm is like the color of the laser. 532 nm is green, 405 nm is purple, 445-473 nm is blue, and 650-660 nm is red. you can't see anything below 400 nm or above 800 nm.
In aus we have the shittest laws known to man and any laser above 1mw is classified illegal and needs permit, any over 50mw even more illegal and considered a "weapon"
If the person pointing looks at the beam,youll see it in almost any condition. and the other end of the beam ..but from the sides barley visible, only in dense fog
It's actually better them one of the very cheap lasers, but what do you mean with ''pop''? when i turn it on, its weak for like 0.5 seconds, then if full. My eyes hurt already only by looking at the beam, not even the dot.
It is very easy to buy a $25 laser and replace the motherboard and laser diode and save hundreds of dollars. You need to know alot about your laser and be specific. Go on ebay and search 200mw diode. They are mostly not in the U.S.A but they are really really cheap and worth the money.
Wont burn skin..but will get warm if held there for long enough..and yes your eyes will hurt and im sure if aimed enough it will ruin vision by some...had if accidentally blink in my eyes few times,,saw tiny bit worse from all that light for a sec.
@mklop100 Yeah its pretty sweet : - ] Not sure what they are called..hmm...the very small circular batteries ..not the flat ones, no idea man sorry. lol. they are sold in almost any store.
it says < 5mw not 5mw. so it can be 3 mw or 1 mw. the other one says < 50mw so it can be 5mw. I have a green laser that says < 5000mw and it can't even burn anything. it's probably 5mw as well.
if your were to grab one of those things that goes into a electrical outlet and do some tinkering aka cutting the wire insulation and exposing the copper then twisting those into the laser diode wires then you could get more power i think not sure tho
If you have the money get a 50mw or stronger,,the strong one i have was from amazon for around 28$..cant find the seller any more. and now a lot of scammers out their saying their laser are this much which they really arent.
Amazon DOT com.. search around. theres different kinds. Mine im not sure from who i got it. its was around 26$ for it. This one is metal heavy and feels well built unlike the cheap black plastic one.
The red laser beam seems less bright because the human eye can see better the color green then any other color. Also >5mW will mostly damage you eyes because the eye reflex is too slow.
I want to get a 50mW laser for teaching my older sister about the stars. Rather than "Okay. You see Orion? Follow Orion's belt up until you see another bright star. UP. That star is Aldebaran in Taurus. Do you see the fainter arrow shape pointing right with Aldebaran on the bottom? I said right, not left! ..." it's much less frustrating to simply point a laser at the sky and show her. This is the one I'm looking at, but I'm probably only going to get it when Christmas finally comes. www.laserpointerpro.com/50mw-650nm-ultra-powerful-midopen-red-laser-pointer-p-200.html
@mustafa2146 No problem..i thiink it mean mila watt..or micro watt..honestly im not 100% sure..something with watts, and how much power and wave they produce.
5mW doesn't mean (Mega-Watt); it means (Milli-Watt) which is super weak. They weren't lying nor scamming you. If you're looking for a good laser, they have one in Japan at about 2.5 Peta-Watts. But if you're looking for one that won't cost you and your grandchildren a lifetime of payments, I'd go with a 6 mega-watt laser.
Guys, i think mustafa has been told what nm means already, he (or she) only needs to be told once..... Pretty good comparison, i have the 5mW< green laser myself and it's rather good, but it does have contact issues.
@fas3000 Hello hello, i bought it from amazon DOT com, i looked up 50MW green laser and found one for 23$. although i cant seen to find that same one any longer, maybe the 5MW's they have on there are as good. but that is where i got mine from.
Wanna know a cheap red laser? £1 red laser lasts 5 minutes and is weak as fuck is not even visible at night. Luckily i got a 5mw for a low price of £4.
I have a "200mW, 532nm" green laser, it cost me about € 15, bought on a tourist market in the balkans (such a laser cost about € 80 in mij country..), but it looks more like a 5mW laser, did they scammed me or did i misjudged the laser?
Hey i need some help, my friend has a real 50mW he got from Amazon and the beam is like TINY and bearly visable at night, although it was still cool, yours was WAY better
none 5mW is the power output and no matter how good that is it's still not very visible u need higher mW buddy but make sure it has an infrared filter or u'll go blind with the invisible light
do TRUE 50mW lazers even come in the pen form? unless Its a mini I dont think they do...sweet vid tho looks like a good place to do a lil sky beamin..just ordered my 50mW lzcs from lazerer cant wait til it comes
@21hdflat Can u tell me the link please? Im seraching lasers for ages and I cant find, because there are a lot and the power is never trustworthy, Ive seen hundreds and I still dont know where to find a good 5 mw laser...
What Laser i can use for Personal defence? i live in Chicago where gun laws are ridiculous and i need something to protect myself with. what is the highest MW that could blind a home invader?
Yeah Chicago is bad I hear, well a legitimate 50mw will be great, but a real one will most likely cost a couple to few hundred dollars. the 5mw might be enough for temp eye pain but not sure if it'll last for more then a few seconds, the more power the better obviously.
+daniel Lamb For self defense, I'd recommend a super bright LED flashlight with a fast strobe. Look into Nitecore brand to see what I mean. Mine will make it hard to see fo 30 seconds after only 1 second blast.
