1 watt 447nm Laser Pointers from Dragonlasers Now Available

[ZapU]

Well if this helps you out at all....My Beam diameter at aperture is 3.5mm and at 3 meters it's 10mm(beam diameter)

Shape: Bar or line.
Battery lasted almost 2 days of fiddling, never on for longer then 4 minutes for burning. Using Lithium photo cells

No optics besides a collimating lens.

Good to know. :thanks:

Just out of curiosity, why DL calls it 447nm if it's a 445nm?

It's a CNI thing. CNI (who makes these lasers) markets them as 447nm, so that's what DragonLasers passes them off at.

445 or 447, it's only 2nm difference. CNI probably checked their diodes out using a spectrometer first.
