I try to send some pictures,or video,to see yourself exactly what it is .Are there some instruction to do it please?
Unfortunately I didn't know anything about the uneven divergence of the multi mode lasers.
I repeated the test to 25m,but with the same results.It means that the 3X beam expander is entirely useless with this laser.But not with the other laser I have,the 1.6W blue one,which focuses way better with the same expander.
I finally turned on the 5W 470nm silver line laser yesterday,had some difficulty to unlock it,and I have some questions to ask.
If I focus it on a wall at a distance of 12.5m,I see a little square,but not so little,as the circle of a 1.6W blue laser which I also have.So,there is a divergence...
I finally ordered 2 Keeppower protected batteries from NKON.nl,as there is not possible to buy batteries from Banggood or Gearbest anymore,so I wait to collect.The laser arrives on Monday.
Thank you for your help.
I have finally ordered a 5W 470nm Sanwu laser waiting to collect it on Monday, and I have been told by Sanwulasers that I have to use protected 18650 batteries .
Because I have a lot of flashlights,(29 pieces, from tiny ones till monsters of 32,000 Lumens),I use many batteries,both 18650 and...
Thank you very much for your response.
As for the divergence which is bigger?I have already a 3X BE to use with the laser which I decide to buy,ie either the 445 or the 470nm.(I think that I will go for the 470nm).
I have three questions to ask please.
1.Is the new 470nm blue, better looking than the 445nm one?
2. Is the 470nm 's diode more robust than the 445's?
3. There is a possibility to choose between one 7W 445nm and one 5W 470nm.Which you think is more sensible purchase?

I want to buy a 6W blue laser,but I don't know many about divergence and possible beam expander good for the job,so I read some stuff here and there but I don't make any decision to buy.
I for the...
