Re: FS: 150mW Green 532nm Laser
Lol, IDK which is funnier, the huge bold centered letters or the avatar:crackup:
I think this is a good choice for a starting over 5mW laser. It has three safety features (key, slide over cover for button, temporary - have to hold button). Meaning that it's not going to be on by accident and if you drop it or something, it will turn off on the way down.
In terms of visibility, outside and night you will absolutely see the beam easily... so will everyone around you lol.
Basically visibility comes down to several factor;
1. Power
2. Wavelength
3. Beam diameter (how tight the beam is when it exits).
4. Divergence (how quickly the beam spreads out).
5. Ambient lighting (the more contracts, for example the darker it is, the more the beam will stand out).
6. Air particulates (if there is dusk or smoke, or even very high humidity, this will allow you to see the beam better).
IMO the minimum for seeing a beam easily is ~20mW. Obviously that's not an issue with this laser (100% guarantee, you don't see the beam at night, send it back
). Beam diameter and divergence are both excellent. The laser smokes dark plastic 3 inches away without any focusing... if you focus it, it does it faster:eg:
Opto is a good company, and if you decide to go with it, I'm sure you will be happy, the only minuses I see is that with their pen
1. you will need to keep the duty cycles shorter (30 seconds if you want the laser to last a long time),
2. it's not focusable,
3. With shipping at least $85 more,
4. The cheap/common looking host.
So let me know if you're interested
:thanks: for looking.
Ill thnk about the 405..I don't have any other "pen" lasers
