Peace,

where has this info come from?
Over at LPF, the vets are splitting the cost.
The pictures are from one of the other vet's suppliers.
The unit will be here next week.
Peace,
dave
Interesting Dave.
I am keen to hear test results re power, wavelength and beam profile.
Cheers.
The ratings are the same:
130 = 2000 lumen
140 = 2500 lumen
150 = 3000 lumen
Peace,
dave
**EDIT** BTW and off topic ;) Hey dnar -- I pulled apart a BDXL writer (quad layer bluray) the other day. The violet diode in it is in a 3.8mm package!
From the earlier videos saying tweaking the wavelength these may be them... Another possibility is that the supply for the smaller package is low since the no-fun-stuff in Japan. Either way I will be eager to see the results at NWLEM Dave!Quote:

Yes, the original 1W diode spec sheet stated a 9mm can.
Hey Daguin
Interesting, thanks for sharing! I hope these can be extracted.
Copied the images for the people at laserfreak.
Best regards

dont the proper ones from nichia have better beam specs, there the ones arctos and the likes use.Quote:

poo then ...
Yep, the previous projector diodes were just the 1W 9mm dies packaged in a 5.6mm case. Have a look at newegg to see where the prices are going, too. It looks like these might be hard to find at under $1000 soon.
Dave glad to see somebody posted the pics over here.
My supplier has not cracked the array open yet to confirm that they have not added epoxy or anything to make harvesting harder yet but I should know when I get it middle of next week. It is going out fedex Monday and I should have them in hand by Wednesday or Thursday. If anyone is interested in doing some testing on these units I have 11 that are still not spoken for.:o
we have one of the 9mm original nichia ones (sent to us for free as a sample, after we bought two 500mw 445s)
can confirm the specs are the same as the casio diodes.
Some additional research this morning gave me some additional insight.
These larger arrays appear to be Casio incorporating blue laser technology into its entire line of projectors.
They do NOT appear to be a replacement for the SlimLine models.
For now these appear to be only in the "Standard", "Pro" and "Short Throw" models
An interesting side note is that with the "Pro" and "Short Throw" models, there is a blue LED in the light path IN ADDITION TO the blue laser arrays. They are also reporting a 3500 Lumen rating for these two models. It will be interesting to see how they combine these two blue light sources in the light path.
Peace,
dave
**EDIT** -- Looking at it more closely, it looks more like the blue LED will provide the blue light and the blue laser array will simply be used to fluoresce the green wheel in the Pro and Short Throw models.
Thanks for the research Dave.;)
I will report back tomorrow night as the tracking shows they estimate delivery of the M140 tomorrow.:beer:
In case anyone might be interested, I have a revised version of my diode mounting block to suit 9mm diodes in the works.
Smooth move Dave, I'll be needing a couple of those.:cool:Quote:

Of course, I was just stating interest. Just shoot me a PM whenever they roll in.:cool:Quote:

That's quite a kick up in the heat sinking, no?
Peace,
dave
Sure is. I am just now left wondering why the different lenses.:confused:
Maybe two things are going on here:
1) More heat sinking
2) Lenses that collect more of the light
This may be how they are getting the higher lumen rating from the same components. They are driving the diodes at a higher current (so more heat) and getting more of the light to the light path.
Did you measure the current?
Peace,
dave
im amazing at the size difference between the two.
if i get any different results from others ill post up if not i wont

Have you measured the lens diameter and the lens projection from the heat sink on the new types, by any chance?
It's possible Casio decided to go for a slightly larger, longer FL lens to improve divergence. That would amp up the brightness particularly in the long throw models.
Its been about a month since the photos of the modules were posted. Has anyone tested the diodes yet.
^^^Yep and they seem like the same mixed bag you get with the A140 to me.;)
.. I still think sombody needs to seperate the lower wavelength ones .. e.g. - 460-465nM .. pm me :p.. I'm still looking for a 488 diode ..
So these diodes are 460 - 465nm, or the same 445nm that we get in the other projectors? If that is true that would be a great improvement towards 473nm...
They are not 9.6mm they are 5.6mm. We just had pictures of the array until I cracked one open. With the larger lenses, wider diode spacing and the original Nichia data sheet said 9.6mm(so we know they existed) we assumed they were 9.6mm diodes. This is not to rule out the possibility that they have a large stock of 5.6mm they contracted for and will be switching up to the 9.6mm at some point.:confused:Quote:

The optimal wavelength for blue would be the 455-460nm range. 470nm+ leads more into cyan.
I have to wonder if 9mm diodes aren't being introduced to stop laser display use.
A larger diode could have a wider emitter and a certain company will know this and know that a wide stripe could make them unsuitable. Therefore I have to wonder if having failed in every other method of stopping harvesting, that company has decided to go with a wider emitter thus rendering the diodes useless for anything other than cinema projectors. Just a thought.
No .Quote:

I just wondered because that certain projector company must be a huge client buying hundreds of thousands a year and if they're worried about harvesting resulting in an accident and that damaging their corporate image, I can well imagine them requesting a new diode package that was unattractive to harvesters where all other methods have failed.
Also, the diode company themselves would appear to have an interest in this as people are getting diodes by harvesting for a few $ when they sell them for laser purposes at over a thousand $ each (last time I saw a purported single diode price posted anywhere on the internet). With so many prof companies as well as amateurs using 445nm it would seem they are potentially losing hundreds of thousands of $ each year to harvesting as opposed to selling diodes for what is in my opinion a ridiculously high amount as a specific laser diode. That alone would surely justify the cost of a re-design and repackage. It would be a shame if they did though as I can't see people sticking with 445nm anyway if they revert back to the high price as people will just look for the next cheapest blue solution and not the diodes, which would probably see a return to 473 as the blue of choice and that in turn would see both the diode company and the projector company lose out in sales anyway.
I don't believe there's any factual basis for suggesting C@5!0 are changing their diodes to combat harvesters.
Oh, I wouldn't be too certain about that... >:)Quote:

The new diode package will most likely be because of thermal considerations. 5.6mm or 9.0mm, people will still use them... What's the issue?Quote:

just put 4 of these diodes into a quad 445 module im building for my self.
exact same beam spec as diodes from A140
I did hear from a knowledgeable source a few months back that there would be a shift from these diodes to bar lasers, in the near future. Just putting that here, since we're discussing it.
I could see that. The companies that distribute similar diodes to the 445s have allegedly been quite steamed about the market shift caused by the sudden availability of 445s for less than 10% of their original cost. Also, see how well these projectors appear to work with many diodes removed. This leads me to believe the change to a different laser format would not be too difficult.

A bar means that you have to remove the heat the whole diode array produces now (~50W) from only 10mm^2. If that would be easy the heatsink in the current devices wouldn't have been increased. TEC cooling is no option, since it at least halves the overall efficiency if not worse. So as long as we don't see cooling water in consumer products I bet we will see no bars.
Quite a lot of the laser industry in low power (<100W) is drifting away from bars to single emitters as well these days.
