    M140 Diode

    I try to send some pictures,or video,to see yourself exactly what it is .Are there some instruction to do it please? Edit. Unfortunately I didn't know anything about the uneven divergence of the multi mode lasers.

    M140 Diode

    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.

    M140 Diode

    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.

    M140 Diode

    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...

    M140 Diode

    Thank you again. So,I think that I will go for a big 470nm laser.

    M140 Diode

    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).

    M140 Diode

    Sorry, but I have many months out of the forum,so I learned about 470nm lasers only today.So,f you can help, where should I "go" to read about ?

    M140 Diode

    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?

    Re: FS: Sanwu Laser store - R/G/B handhelds x3 BE & Stainless steel "The Spiker" rele Do you use another diode for this than the NUBM44 one?

    Re: FS: Sanwu Laser store - R/G/B handhelds x3 BE & Stainless steel "The Spiker" rele I see that those meters from this store have color compensation while eBay's don't.

    Re: FS: Sanwu Laser store - R/G/B handhelds x3 BE & Stainless steel "The Spiker" rele Hi guys. 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...
