FS: Lasever 500mw 635nm red

[andy_con]

i love my new 380mw 635nm from lasever

yeah, but that is not saying anything about the divergence.
If you have the time can you measure the diameter of the beamspot just after the laser and on a few meters distance?

In response to your PM to me about measurements, here you go.

Coming out of the head 1 inch away from the head, the width of the beam is 1/4 inch
25 feet away from the head the beam is 2 inches wide 1.25 inches tall. Ok so now someone do the calculations figure out the divergence.

Thanks for letting me know !

Here you can easy calcuate the divergence.
Looks like around 3.3mrad // and 5.8mrad _|_ .

I'm not sure that is fair, those Lasevers are focusable. I bet it is not at the most optimum focus. I would slmosst rather have a Lasever than a CNI for these fatty beams just because it is focusable.

That is true, this is the setting it came from the factory

СNI is focusable too.
Also from this picture
I can tell that it's collimated properly. Thats the best you can do with those torches.

Thats right DrLaser. Its the diode type and not the setting. Thats our problem with red "highpower" lasers. Good beamdiameters=highprice. Lowprice=china lasers with wide emitter.

[Dr Laser]

Nopes there is no such a thing as single-diode-highpower-good-beam-spec.
Once you get above 200mw @635nm beam spec goes to wild zoo. Thats the nature and there is no difference between China cheap and Germany expensive.
Only way you can get a good spec is with a big array of below 200mw diodes and a beam expander. Because in this case there are multiple emitters used, beam spec can be very good. Thats how Arctos and other people do their monsters.

Sold !! to Joe Holloway $865. Who is Joe?
I bid twice on it when it was in the 300 range.. Too rich for my budget..
Congrats Joe, 1/2 Watt of 635..Mmmm... yummy

All good but I would not touch Lasever products with a 10 foot pole. Wait give me 20.
