Where should I buy my laser?

[ChaosLord]

Well, unless it's laser related....

I know this is a noob question, but will I be able to see the 100mw 532nm beam in a lit room?

 

[Shakenawake]

it really all depends. the angle you are viewing the beam from makes a huge difference. imagine a line coming straight out of your eyes. if this line is 90 degrees in relation to the laser beam, it will appear much less visible. the smaller this angle, or larger, depending on how you think about it, the more visible the beam will be. so 1 degree, or 179 degrees, would be the brightest, though I doubt one could manage such an angle without pointing the laser right between their eyes. finally, the more particles in the air, the more visible the beam will be. In star wars we observe colored lasers in space, but in fact you would not be able to see the beam in vacuum

the short answer, yes, it will be visible in a lit room, but there are factors that determine how bright it appears to you
20 degrees is pretty small, the beam would certainly be visible

 

[ToneLoke]

Say I view it from 20 degrees pointing away. Would there be a visible beam?

 

[ChaosLord]

Depends on the lighting, particles in the air, angle of view. In a semi-lit room my 151mW 532 is easily visible. If sunlight is streaming in through a window, you might not see it.

Max has not shipped the laser I ordered on the 9th. Should I contact him?

 

[Livinloud]

he most likely shipped it and hasnt updated the site, he shipped mine this morning and emailed me about tracking. id let it wait a little but you can email if you want to speed things up.

 

[ToneLoke]

I haven't recieved an email from him saying that the laser was shipped.

 

[Livinloud]

he normally doesnt email you, just updates the order page but since my laser was returned he emailed me to let me know he re-updated the order page to show the new shipping info

 

[ToneLoke]

I ordered the laser with a guest account. How would I know the laser's status?

 

[Livinloud]

guest account? i didnt know you could do that? hmmmm contact max then

Actually someone on lpf made a calculator to find how long a battery will last. (and some other stuff)

I don't have the knowledge to say if it is accurate or not.

btw the whole 2nd page was just you and me LivinLoud!

mah means milli amps/ per hour if your device pulls 1800mah like my 445nm laser does... than my 3400mah Panasonic battery will last a little less than an 2 hours... 3400/1800=1.88-

Batteries got here today. I might use a multimeter to test them later.

 

[Livinloud]

what ones did you end up getting?

EDIT: just noticed orbtronics is let 10 minutes away from me, maybe ill stop in sometime and see if they have some more batteries of goodies

 

[ToneLoke]

I got 2400mah trustfire batteries.

ohh yeah, now i remember. would be interested in what you find when you test them
