blue, green, red, and focusable

Postby wthierry » Tue Mar 25, 2014 4:37 am

Can someone give me some tips on lasers to use? Right now I am using a red line laser level, about 40 dollars from home depot, but I was wondering the results with the others, and also suppliers that sell them? I would prefer focusable lasers as well. The objects I scan are usually 6-10 inches high and sculptures,or figures. I am still learning the software, and see so much potential in it. I am really excited about this stuff.

thanks
wes

Hi Wes,
A focusable line laser will improve the scan result.
Regarding the color: I prefer green, it's better to see for a color camera than red and not so expensive as blue lasers. Its line width can thinner be focused than red ones:

Power: 5 mW is fine for objects up to 1m.

From where to get: You are probably living in the U.S., so it's very difficult to import good lasers from abroad because of very strict import rules.

But here are some U.S. DAVID resellers:

PS. If you intend to test DAVID with cheap line lasers, so have a look on Apinex.com lasers.

Edit: I have just taken a look at the DAVID US resellers sites.:(

I have another question about Lasers -

Do you have to use a line laser?

Can a laser with a grid pattern be used?

Sorry, such multiple line laser projections are not supported by DAVID. You've to stay with single line lasers.
