I am looking for a green laser pointer. I see 532nm and 520nm is out there both are advertised as a green laser. Just wonder what is the differnt betwwen two and which one is better. Thanks
hehe answers the full question-the wavelength is different..
-the electron volt is different.
-the frequency is different.
- the 520nm is slightly bluer than 532nm.
-the 520nm is direct diode while 532nm is dpss.
- 520nm is more stable.
-the 520nm is harder to damage.
The 532 is a laser and the 520 is a flashlight.
LOL, but seriously if it's a multi mode then do not expect a 532 style round beam, The MM 520 directs make rapidly diverging rectangles, but you get used to them and they don't look that bad, well there's the artifacts and the splash, but you can make a lens flare hider and clean some of that up I'm sure, just like the 445 lasers, basically a 520 in a say, NDG7475 is a bright green version of a M-140
Really, the only deciding factor should be which color you like best. Quality 532 laser won't take too long to warm up. 520 and 532 are almost similar except for 532 appearing a little more greenish-yellow.Thanks. So which one will you guys recommended? Cos I am going to have either one soon.
That's like saying 12 year old scotch and MD 20/20 are almost the same, they are both wet and get you drunk.Really, the only deciding factor should be which color you like best. Quality 532 laser won't take too long to warm up. 520 and 532 are almost similar except for 532 appearing a little more greenish-yellow.
What is your budget? <$300 and you won't be able to afford most 520nm lasers out there. $300-500 and I'd say get a 520 nm. >$500 I'd say to get a high powered 532nm from jetlasers.Thanks. So which one will you guys recommended? Cos I am going to have either one soon.
