Can some one tell me whats the best IR laser and were can i find it?
Thanks in advance
Btw i’m in the mid of my project i’ll post pics about it later

I was wondering the same thing. I’m really new to this laser thing.

I was looking at a 780nm 10mW 3.2VDC 12 x 30mm Laser Module and wondered if it was ok. The part I want to know about is 10mW is that too much?

It depends on the size of your screen and the laser line angle. I’m using 2x 10mw lasers on a 118x74cm screen with a 120% angle lens which is just enough to get the blobs recognized and get through the tracing paper.

ok great. Your using 2 at 10mW. Are they 780nm or 850nm ?

both lasers are 850nm.

Although i did order 4x 20mw laser of 780nm so see if the extra strenght will give better results. But maybe it would be enough if i spend some more time aligning the 2 lasers i have better..

I found a place that sells them cheap the 780nm. I was going to get like 8 of them w/ 120 degree angle line lens. So now I might get them after all.

I just ordered some off aixiz.com too see if they deliver any good stuff.. they’re so cheap that its worth the risk of using an unknown shop
The specs you posted seem as if they come from that website also

you are right it was from that site. Are you getting the 10mW 780nm lasers? w/ 120 degree line lens?

Yes, except i’m getting the 25mw ones.. my plastic foils blocks too much IR light and i need to use a couple a touchlib filters to get the blobs recognized. Not nearly clear enough blobs as AlexP has, so i thought i would add 2 extra lasers, but then i saw the 25mw ones so ordered 4 of those....

Anyone had there lasers shipped yet from Aixiz.com? Mine are still “Processing” .. :(

I guess i’m expecting people to always ship within 2 days, i only ordered them the 10th..

are you in the US? were are they shipped from?

I’m in the netherlands, but the status was updated friday (or saturday) from pending to processing, so atlast something happened
According to the info from there website they are based in Texas. (woman owned / veteran owned,lol odd line for a shop/website)..
