A-140 vs. M-140 vs. H-1600

[steve-o]

If you can't get to it next week, I have a guy with a SEM that will take some shots for us. I was going to have you send them to him after you were done. If you can't get to it before you have to leave though, I would ask that you let me know. I will get his address to you so you can send them to him before you go, please

Peace,
dave

No problem. PM me his address and I'll have them ready to go.

DTR, did you test the 9mm diodes with the lens that comes stuck on the face? if so what was the beam like?

I have a pair to test but not got round to it yet, was just wondering if there's any point to keep the lens on while testing.

Ahh and which pin is the anode.

[DTR]

I only powered one up with it and the beam looked pretty decent but no I have not done any testing. I have heard from some of the others that the lens is equivelant to a G-2 as far as how much power it passes.


Here is the pinout. Use the indention's to get orientated.

OK, as luck would have it, I worked in Lab 3xx today, and had access to the microscopes. I had just enough time for 3 quick-shots. The 1st 2 are the 9mm and the 3d is one of the 5.6. (don't know which- it was a rush-job.) Hope this helps. Now they're off to Cal-i-forn-I -ayy for a SEM session :]

SWEET!
Thank you

The third one is the M/H-series diode
The A-series diodes only have three wires

On the 9mm diode, where the ESD component is attached, there is a "rough" portion or "pad" under the component
On the 5.6mm diode the rough portion or pad is in the same place, but there is no ESD component or wire

Great shots there SteveO.

Here's my shots of the 500mW Mitsubishi.

Welcome somebody to put my shots and these others all in a folder. Or the wiki

Sorry for the lack of updates here

The diodes are in the hands of the gentleman with access to the SEM
His preliminary look said that the die and window are the same as the M and H series diodes from the more popular (and less expensive) projectors
He is going to get some better measurements and try to get measurements of the wires yet

I have not seen anyone publish a good IP/OP graph yet
However, in the few hand-helds that have been built with these, we are not seeing any significant differences from the M/H series diodes
We are already regularly exceeding 2W with the less expensive (5.6mm) diodes from the M and H series diodes

Peace,
dave

**EDIT** -- I just checked. The pictures are up over at the pointers place. The dies and facets are identical

After looking around the possible sources for the 9mm diodes are BenQ´s or Acer´s new projectors.

I'm sorry. I thought that this was already public knowledge

We got ours from a BenQ LX60ST

THank you for the confirmation. How many diodes are inside?
