Hello,
I wanted to ask if there is any beam difference between 520nm and 525nm
Does one have a tighter/better beam than the other? like different lenses or something?
because i want to buy a Sanwu 1.2W green laser but i have an option between the two
The 1.2W 520nm is 40$ cheaper than the 1.2W 525nm and i have no idea why
thanks in advance
