feed me knowledge

[xxspeeddemon69x]

so i have searched and searched and i am unable to find a thread that contains exactly what i am looking for so your vast knowledge would be appreciated

i have purchased a few cheap ebay lasers and am not too impressed not much more could have been expected

so to the point how many mw of each wavelength gives you:

a nicely visible beam(without smoke)
lights matches
good visibility at a long distance

thank you in advance for your help :beer:

To answer your questions:

First it depends on the wavelength. For the answers below I will be using 532nm

1) 75-100mW
2) 100-150mW
3) 100mW

thank you greenlander what about 405nm 450nm and 650nm

I don't know much about those haha, sorry. I would hate to give you invalid info

That info is readily available on the forum. There is a trick to the search bar here.....dont use the one listed as "search", use LPF search and you will get MUCH better results.

LP 515nm 532nm 1-150 would this laser with the 100mw work

Yes. Do you have safety goggles too?

 

[Livinloud]

lighting matches requires either brute force in power or focus-ability of the beam. Those pen hosts lack both

http://www.laserbtb.com/productshow.asp?id=77 200mW of these should light a match with ease, FYI you will need PROPER laser safety glasses and those will set you back $45 shipped

100mW of the above link will work as well but why get 100mW when you can get 200mW for just a little more :eg:

FYI, ALWAYS ADD THE IR FILTER!

that link doesnt seam to work...

 

[Livinloud]

Hmmm, its the exact URL. Anyways its just the HL532 model from LaserBtb

EDIT: link works for me, try again?

 

[xxspeeddemon69x]

hmm that was weird it works now

is there anything cheaper around the $100 range not necessarily 532nm

 

[Livinloud]

does it need a key switch?

Joker is a great guy despite his name :crackup: iirc its $50 shipped to the US

 

[xxspeeddemon69x]

not if it doesnt need it to get into the states

 

[Livinloud]

above post ^^

Ill vouch for joker and his lasers. I have one on me right now. It's overspec, solid, and incredibly stable. ( it's is a 650)

 

[xxspeeddemon69x]

thanks tmack

livinloud which one were you referring to the 532 or 650
