At the very least it is a very bad example. I gave the wife a verbal lashing for getting my face on camera!

Default Re: 2.5w 445nm laser.

I just bought (and received) this from DK- it works fantastic- build quality seems great, though I didn't open it to look inside (external machining looks nice, and the host is solid, no rattles).

I metered it on my radiant alpha- surprise! Maxed out my meter at 2W

Maxed it out quick, so 2.5W avg. is a reasonable figure

It does burn quick- burns better with an out of focus beam than my 1.5W does focused.

THe heat sink is probably overkill- during a 25-30 second test the host didn't get warm at all- but then again it's huge!

-Dave

PS- I DID wear goggles for the test I'm legally blind in one eye, so I have to be extra careful..

DK, you probably want to use some goggles when you measure that thing on an LPM....

I foresee many great builds coming in your near future. I'm looking forward to seeing what hosts you will be bringing to the forum. It sounds like you've got the bug.

Default Re: 2.5w 445nm laser.

I really just like to tinker. I have access to all kind of large mills and lathes at work and a massive 8x16 cnc router not to mention every tool I the world for sheet metal. I built my own cnc router a while back a 24x 48 model. I have pics of that if anyone is interested. Otherwise I just have a 7x14 mini lathe at home. I am a regular over on candle power forums as well. I understand just enough of this to make stuff if it has already been done before and there is a parts list already out there. I like to get stuff a perfect as I can. No half ass goin on over here. I appreciate the confidence and praise.

FYI I made another host identical to this one and I ordered the 2 diods from DTR at the same time. The other diode is not tested but I am expecting it to lay down comparable numbers. Of corse you never know until you test it.

You can hope, Out of the 8 or so M140 diodes I have received only 2 have been able to hit 2.5, others 2.2-2.3 and then a couple at 2-2.1.

In the test video I know it only hit 2513mw but I tested it before and it hit 2566mw and right before I boxed it up it hit 2540mw I am positive that I could of placed it closer to the sensor and focused it a bit more and cleared 2600mw.
