de-canning tool. the one sold by thor

Ahhhhhh! Thor = Thorlabs ;)

Yes. That is the tool I have

It takes about 10 seconds to de-can a 5.6mm diode with it :)

Peace,

how does it work?
You just put the diode in and turn the wheel and after several rotations it cuts or is it just one?
I was wondering how it worked and if i could build a diy one with a easy way for others to do.

On a more personal note -- ya gotta love how cleanly the de-canning tool removes the can :san:

I can still see the sharp rim around the diode. :whistle:
Thank you for providing the diodes.

I wander the strange 4 wire configuration of the H1600 and the square layer below the wire in picture 9. Could it be extra IC logic ? :thinking:

It works like a tubing cutter, but it has wheels to hold the diode inline

You're welcome

DTR found some mention of ESD protection in (possibly) these newer diodes :thinking:

So the M and H diodes can handle more current, supposedly. Has anyone pushed one to the limit? How much more output do they have over the As? 25% more?

On average, I think 25% more output power is a fair assessment.

At least with respect to the H series diodes I've tested, they can handle up to 2.5A of current (so, yes, I guess about 25% more of that too). But there really isn't a compelling reason to push them that hard.

There might be a decent argument for pushing them to 1.9A or 2.0A now, but not 2.5A.

I would also note that when Lazeerer replicated my H-Series testing with M-Series diodes, he had diode deaths, whereas I did not. I only tested 3 diodes, but I believe he did too (and he had one death among them, and one diode that would have diode if he had pushed all the way to 2.5A)

So the H diodes are binned higher then maybe but other than that should be refereed to as the same as the M?
I am interested in getting one of these new H diodes to run a 1A in my projector that way it will have a long life.
 
Wow, thats impressive. Although I've never really been "power hungry" when it comes to lasers. My 800mW 445nm is plenty for me. lol.
Nice work guys. I'm sure this will help out alot of people.

If the M and H diodes are the same, what justifies the difference in pricetags? There are more diodes in the M projectors (32 vs 24), so are the H projectors more expensive than the M ones? And if so why on earth would anyone buy the H diodes when they cost more and from what I can conclude from this thread are the exact same ones as the M diodes?

Best regards

EDIT: Pricetags

445 M140 Diodes $45
445 H1600 Diodes $59

The H-series projectors are more expensive than the M-series. They have more diodes 32 vs. 24, but not enough to justify paying a premium for them.

We do this sort of thing (buying different pieces of equipment and examining the diodes)as part of our hobby.

Once one has bought the equipment, we try to recoup some of the cost by selling off the excess.

Even when we discover no difference (like here with the "M vs. H") some members are willing to help us cover the cost of this knowledge by paying a higher price for the initial research ones

Of course, after the initial research is done, the members here are knowledgeable enough not to pay more for the same thing ;)

It not only helps the hobby progress, it helps protect the members here from being ripped off by unscrupulous sellers.

We now know that the M-series is tougher and more powerful than the A-series, but the H-series is the same as the M-series.
We also know how to tell the A-series diodes from the M-series diodes from the square code on the back

Up to this point, members should be willing to help the ones doing the research to be able to afford that research. After we have established the fact, members should no longer pay to difference in price where no difference is noted

Peace,
dave

That makes sense :beer: Thanks for a very thorough reply.
 
Yup back in the day we did the same thing with the xj-a150 vs the xj-a140.
Speaking of that my xj-a150 is still alive and doing well in my laser harp.
Any one else got a a150 diode?
