Hello, to everyone. I am new to this forum and I d like some information.
I m planning to make my first laser spirograph. I know some things about lasers and i have seen some tutorials about making a laser spirograph. I have heard that a laser of less than 5mW is safe enough for the eyes. However, I wonder if a 1mW or even a 5mW laser would look good. I mean will the beam be visible in a dark environment? I am afraid of buying a more powerful laser due to safety reasons.
Thank you in advance. I hope there is not a similar thread (i searched the first pages and didnt find nothing).
