Ok, this is an idiotic question... But I have to ask it.
I have seen people shining lasers into devices which split the main beam into many smaller beams, casting a grid pattern onto a surface. I would really like on, but a half an hour of googling has not been succesfull at finding out what they are called... I feel like an idiot for having to ask but... I dont know who else to ask and if anyone knows what they are and where to buy them it will be you guys.
I have a 1W 445nm hand held which I would like to use with it. Do I need anything special? Or will anything work? Are they expensive? If so can I make one?
Thanks!
