Thanks.
I did get a quote For red 100mw, the sample price is 216$/pcs. This is portable and the battery time is about 3 hours. The rating is 3B. Just a little concerned on safety. I will wear it in a fixed position and hope that this will not be considered unsafe
Thanks for this. I did have a look but need circle of 1.5-2.5 metres diameter. It will be portable attached to a pole.
I had contacted Civil Laser who said that the laser could not be powered more than 2 minutes. Strange.
Anyway I have the right idea but ask for anyone who can put me in the...
