I have my parts on order and have a few questions now while I wait
1) will the laser burn as strong 20 feet away as it will 2 inches away from laser
2) I read that a plastic lens will melt when using 405 at about 500mw because of the heat. There are alot of glass lenses out there from $8 on up. Does it really matter on the price of the lens as long as its glass
3) If Im trying to burn a white peice of paper 8 inchs behind a peice of glass will ghe glass have any efect on the beam
4) Would I be better off buying a good driver instead of making my own
5) Alot of people here state the importance in using glasses while using a laser. Is the beam of a laser really that bright to look at as long as you dont shine it directly in your eye.
6) Can I use sunglasses
I hope thats not too many questions
Have a good evening
