New 9mm 445 diodes

Meh, I'm not sure it worth the extra $$. Not at a retail level anyway. You also have to consider you need a machined barrel to hold the new lens too. Thats even more money. Its a lot of extra money for a few hundred mWs of power.

Great job Angelos, and Jordan. :beer:

You got it buddy. If the projector was 400-500$ cheap it would be Great.

It's glass... AR coated as well.

Maybe you got that 'gel' feeling because of the spots of glue on the lenses from the way they were mounted. (I just carefully scraped off the glue)

I did some initial testing and comparing with 405nm and 445nm. Very close power comparisons with the 405-G-1 power as you mentioned.

As you also pointed out, I did notice a very sharp focused, pin point dot with blu-ray.

It is a little more 'close focus' in design vs the 405-G-1, and that is why the focus is more 'touchy'.

It will also mean a little more adjusting depending on distance and so forth.

But it is a nice lens.

For 445, I can see similar 'side splash', which was expected with such a close focus lens.

I did also notice the two long 'wings' that we saw with the other Ca$io lenses. But not near as noticeable.

Seems to be a pretty good lens!

The Gel Feel was from dropping the Lens and the way it sounded. It did not sound like the G1 lens is what iam saying. It sounded like my Geltec lenses. Should have said that then it feels like Glass/Gel Like.:Tinfoil: Nothing wrong with that But Just saying it sounds more of a Geltec lens then a G1 does. Iam sure you know what iam talking about.

Thanks for the Testing +3.:beer:

I'm confused about a few things.

1. Price. Isn't street price about $1,850 for one of these? There are 24 diodes. My handy calculator tells me that comes to about $77 each - BUT they come with a very good $58 G-1 level lens. I guess if we decide that an A-140 is as good as an M or H then then the A series is cheaper, but wouldn't this combo be cheaper than an M or H + a good lens?

2. For a 405nm or ~650nm burner, is this lens giving a better burning dot?

3. With 9mm packaging, won't heat sinking be better?

4. Why is the 4.8v such a big deal? I'm still working on understanding the circuits better, but is this a universal problem no matter which driver you use or will it affect some designs (buck/boost/linear) differently?

5. Daguin decanned this diode and it has ESD and if I am not mistaken, he is wanting to measure the bond wires as he thinks they MAY be thicker? Those two things could potentially lead to longer life and fewer DOA's.

Thanks for any help!

1) $58 for a G1 lens ?!?

I think you're forgetting that the lenses in this projector don't come in convenient M9x0.5 mounts ready for use. They're the bare unmounted glass. So compare them price wise to the bare unmounted G glass, which is $20 or so.

I was not aware that the glass alone was offered for $20. Is that from Jayrob too? That would save me a lot of money. I have a bundle in just lenses right now!

I saw Hak's post

Blank glass lens mount 10 pack for AixiZ 12X30mm units, AixiZ

AixiZ 5 pack 15x50mm for 9mm diodes Housing Blanks, AixiZ

And was assuming it would be very easy to package these lenses.

Not really. They are $25 each plus shipping for the bare G-2 lens and if you wanted to use the Aixiz blanks you would need to machine them out like Jay does as if you just try to mount them in there the top cavity it is too big for this lens to be centered. You will never get it straight. I don't use the Aixiz lens blank. I use a different one that I modify to fit the G-2 lens and allow it to reach focus before bottoming out.



On the 9mm diodes could the ESD protection somehow account for the slightly greater forward voltage of this diode?

I think Jayrob sells the G glass alone for $28

EDIT: DTR beat me to it

ESD Protection for diodes seams to be mainly needed for low power girly single mode diodes. These more modern higher power Mitsu and Nichas seam to be quite tough as nails, tougher than even gingers lazyorbs.

Why would they waste their time/money doing it if there weren't some advantage?

These lenses do not fit correctly in a AiXiZ lens holder. The lens need to be closer to the diode.

They maybe $77 is you buy the whole projector. But typical retail markup, plus the cost of matching the barrel, brings it to the point its not worth it. You might as well buy a 5.6 445, and a G1. You'll be saving ~$50.

EDIT: You guys beat me to it.

I think the ESD protection is probably just a 1k resistor or something simple like that. Could you try measuring the resistance between the two leads?

It is what i was thinking.

If I can cut it off I would attempt it to see. I got to talk to Joe and see if he wont mind putting under the Microscope for me and doing it.

Is it worth doing. Probably Not my boost drive can supply the currant still i just tested it but Still others might have problems.

So doesn't that HELP my case? The bare lens is nearly $30, or is there a $20 option?

Also, without starting lens wars two, I don't know what all the differences are between the two. I have ordered G-1's from Jayrob and I've ordered a fair bit of diodes from DTR so I try to spread the wealth.

But DTR, since you do lenses AND diodes, wouldn't this work well for you?

If you can get a lens and diode for $77 and then just package the lens, seems like you are coming out ok with this setup as an alternative?

Again, we get better heat sink properties, some sort of ESD and perhaps better wires. And the lens may have good burner properties.

I guess that I don't want to throw this out too quickly. Maybe I should let it go.

I just answered this question in another thread, but since the topic is also here, I want to post this information about the mounting of the 405-G-1's...

Here are the main reasons that I go through the extra work for my mount:

* Able to enlarge the entry aperture and allow more light from the diode into the lens
* Able to set the lens 'lower' in the nut, so that it can get closer to the diode if needed
* The lens is perfectly centered in the nut (if just mounting it in the retaining ring end of the nut, there is a possibility that it can get off center)

As you can imagine, there is a lot more work involved with the way I mount the lens.

* Machine the lens nut to fit the diameter of the lens
* Enlarge the entry aperture
* Make the custom sleeve/retainer tube that is needed to hold the lens in place...

*facepalm*

You're consistently comparing retail (or "hobby retail") price to raw component cost. If Jayrob sells the bare lenses for $28, do you think his cost is $28?

We're evaluating the projector here, which is the supposed source of these new potential lenses. So if you want a meaningful comparison, you have to compare items based on their cost at similar stages in the chain. If someone like Jayrob or DTR were to source lenses from the projector, then you should be comparing the price of those lenses to whatever Jayrob or DTR would pay for 24x of the G lenses from their suppliers. I'm assuming (and don't know this for a fact, nor care, nor do I want an answer, nor is it any of our business) that if Jayrob can sell the bare lens for $28, he might be paying somewhere around $20 for it.

That's what you compare if you're talking about the price of a raw lens source to the person who would be doing the purchase. If you're talking about harvesting a projector yourself, then there are all sorts of other things you would need to adjust in your comparison. Like, for example, the price of a 5.6mm diode. Because your 5.6mm diode is no longer $45.

People never do price comparisons right around here. Pet peeve.

EDIT: Here. Compare the part costs if you were going to do this right. If the price of a raw G1 lens is $25, then -

(5.6mm and a G1 bare lens)
= ($900 / 24) + $25
= $62.50

(9mm with it's included lens)
= $1850 / 24
= $77.08

But I would say these are more on par with an H1600
Which DTR is currently stocking, this new projector would probably be a better choice than the h1600.

I dont see it replacing M140's but I think it has a place.

The problem I see is that there isnt realy a soure of aixiz sized modules to put these in

The M140 and H1600 haven't been conclusively proven to be the same/not the same diode... Or just a more efficient bin of the same diodes.

Also, there is a source of 12mm modules for 9mm diodes.

In fact, I think it is more likely that M = H.
