is it true - burning hole in vinyl from 150feet?

[alibaba2]

is it true that a 2500 mw IR 808 Nm will burna hole in a thin vinyl sheet from 150ft?

is this possible without telescopic adjustments...just wondering?

well 2.5 watts of any laser would do some hefty damage if focussed correctly

IR has pretty bad beam specs (from my understanding) that without beam expander the divergence is so bad that at that distance, the dot would be too large in diameter to burn a hole, but, could possibly make it smoke a little. :-?

its possible but with damn fancy optics (beam expanders, special 808 glass and a fewminitues tweaking the lenses) if you feel really special get some C02 lenses and give it a try with 60 watts ( even if its a inch big at target its still goin to wreak it)

The longer the wavelength the more scatter you'll get from the beam, and the harder it is to focus into a beam w/ low divergence.

Maybe 2500mW of Gamma Rays!!!! Muahahahaha!!!! (Dr. Evil laugh)

At close range its easy but at 150 feet you will need some sort of beam expander.

Yes, but what he said. I.e. telescope. Also a high NA collimating/focussing lens of large diameter, say an inch at about 3/4 inch from the ld may work somewhat.

2.5W dont know if its that imposible at all, to be IR is suposed to be better than normal? I mean a 2.5W would burn it at any wavelenght!

2.5W??? are u crazy ...?of curse u can burn if you want with this laser,i watched a vid with ir laser 3W and he can lights matces from 200 metres away
