Default Re: 510nm Green Laser Pointer For Pre-Order!

Bootleg2go, I think you are misunderstanding how these projectors work.
It's not like the DLP projectors that simply need a huge amount of light,
no, in these pico-projectors the acual laser diode scans each pixel of the image.
So you only get 3 diodes in each Picoprojector (otherwise they wouldn't be so Pico, now would they?)
a red, green and blue each. A little beam combining RGB module.
So no way these direct green diodes are going to be had for 40$ each.
Because of the same reason, I think the beam spec might not be that bad after all.
I'd assume it is single-emitter given the low power.

Also, why would it be several months after mass production and delivery starts?
I'm pretty sure the projector manufacturers had plenty of time developing prototypes
from available engineering samples, and likely are just waiting for the green diodes to arrive....., no?

Well beam specs and price will be known for sure after the projectors with these diodes are released and someone cracks one open or something. I also do see these coming out before the end of the year. (guess)

The Way this is Being Presented These diodes WILL come Available to Us. He is Obviously conscious of this Fact. Don't waste your $$ on this Noob. He Obviously doesn't want to be Part of Or Help contribute to our Community. Let him sit around with a nice surplus of these Diodes to Sit On... And then after we start using them our selfs and making our own Units he will be forced to lower his prices and he will loose the maximum amount per what he invested. It's Only what people like Him Deserve...


Thanks for the Information my friend, We are Very Happy you have giving us the News that we can start making our own 510nm Soon! Hope you find a Way to Make some $$ because your Obviously Desperate...

Hi anselm,
You're right, I misunderstood, I was think projector, not pico projector.
That said, it may only only contain 3 or maybe just one diode. Remember the larger projectors don't need red or green, they do it all with blue. Or there might be just a few of the green ones with no red or blue.
Another consideration is that they might not even be harvestable, they might not be packaged into discrete packages that can be removed. They night just integrated into a small IC due to the very small space allowed We'll have to wait and see.
The 445nm diodes are single emitter as well, so these will probably be too, but I wouldn't bet on better beam specs at all.

It would be several months after nichia goes into volume production for many reasons.
Volume production doesn't mean they are at the customer ready to use. The process of build IC's which is basically what they are, requires time put all the layers into silicon, which can take weeks. So the projector companies would probably not get them for many weeks after they go into production...maybe even a month or more depending on the number metal and silicon layers in the process.
Volume production of components is not the same as availability.
Then even when the projector companies get them, they don't just slap them on and ship them. They need to go through many levels of product verification and testing like shock and vibe, accelerated lifetime testing and so on. This is because a small failure of any component within the warranty period, means they lose money on the item and a design flaw that results in an early failure of even 1 in 1000 can ruin a big company making millions of them.
I've worked in the high tech manufacturing field for nearly 30 years and stuff just doesn't get thrown into a new mass produced product and sent to market in a month or three.
Take a look at Nichia and when the announced the 445nm diode as going into production and then when projectors finally where in a store with those diodes, I bet it was more than 6 months time and maybe even close to a year.

Having a few engineering samples helps a little, but the real testing and integrtion into a product doesn't start until there are production parts.

My advice is to wait until there are real diode available and then decide.
I agree... $300.00 for 50mW is kind of steep to the general LPF
public.. (I'm sure a few with jump in to be the 1st)..
I also agree that these LDs are probably already destined to be
installed in some new products... and as we saw with Kasssio...
We can no doubt get them a lot cheaper buying an end product
that uses them down the line...

I personally have no need for a $300.00 50mW green LD...
I can easily wait for a better deal...

Now I don't know so tell me if I'm Wrong... but Doesn't the larger units uses 445nm because it's easier to get the color spectrum from? And so it's wouldn't Work the same with 515nm? Or am I Mistaken?

Default Re: 510nm Green Laser Pointer For Pre-Order!

at bootleg, the larger projectors don't do it all with blue. Remeber there is a large Red LED in there. and the odds of the lasers diodes being re-housed in special ways just for a pico projector is slim to none.

@ krogith, i am pretty sure a green dpss isnt used in the crapio because dpss isnt very good with hz and Mhz modulation. so the direct drive 445 and a phosphor wheel works for this. so, if the 515nm diode come available i still doubt we would see them in the larger projectors because of out put power issues.

Hi Michael,
I'm for sure not an expert with these projectors and have never even taken one apart.
Maybe someone else can chime in as to the purpose of the red LED in the big projectors.
As for package size, these 510nm diodes will need to be in a much smaller package size to be fitting into things like cell phones that are only maybe 5-6mm thick on the outside, they are not going to be in the big discrete cans like they are in the 445nm projectors if they are going to be used in the small products like cell-phones.

Default Re: 510nm Green Laser Pointer For Pre-Order!

I'm guessing the powerful red LED is the red (obviously), and the 445 is at such a wavelength to still be relatively blue, but easier to fluoresce into green shades than 473nm, therefor it acts as the green and blue. Then it's just a matter of powers at given times and color mixing.

Please note I'm talking out of my ass. And what better place to talk out of my ass than this thread lol.

^^^ in the projectors that are harvested, the 445 is used as blue, and as green. but in the green sense, the laser lights up a phosphor wheel.

I'm not quite sure how this isn't very obvious to everyone.

Sheesh... There's a lot of hostility here.

I see no reason why anyone would expect mind ripper to be a scammer. Has he done wrong in the past?
Actually, I recall mind ripper once offering CNI products in the past and at a good price.
I think his sale went well.

All of these defamations are based purely on speculation as far as I can tell.
So the guy isn't familiar with the multiquote button. Get over it.

Does anyone know which product these green diodes will be integrated into?
Does anyone know how much that product will cost?
Does anyone know whether or not there will be an "easily available" source for the diodes?
No.

All I see here is a bunch of boys getting all fired up on testosterone over something nobody has any clue about in the first place.

If anyone is expecting to crack open a $800 projector and find 24 50mW 510nm diodes like the 445nm diodes, I would have to say that that is probably not going to be the case.
If you think these diodes will be had for $40 a pop, only time will tell, but most likely not.

Personally, I'm not really excited about this.
Based on what happened when the 445nm diodes were discovered, the future of this hobby is disappointing. This forum is more of an advertising/sales platform than a DIY oriented knowledge base.

Lasers have lost much of the novelty they once had.

Anyway... back to my point...
Why is mind ripper a bad guy for offering a unique and new product?
Yeah, so far there is little information on it but what do you expect? Many companies are anticipating this new technology so why wouldn't CNI get ready for it as well?
As far as prices go, I think the companies that are making orders for these diodes have a better idea of what they cost per unit than we do.

Did everyone forget about the Arctic fiasco? Wicked advertised the Arctic as if it was in stock and production had hardly begun. Everyone still bought 'em up.
What about the Dragonlasers 447nm Spartan pre-order? That turned out ok.
At least mind ripper is kind enough to let us know that (1) a 510nm diode is going to hit the market soon and (2) CNI will be integrating this diode into its products.
It has been made clear that it is a PRE-ORDER and you can get a refund at any time if you don't like it.

Is everything a scam these days? Is LPF getting paranoid?

"easier to fluoresce into green shades than 473nm" That's what I said

I am aware this is a troll thread. What else could it be at this point

Yep, unfortunately, most definitively. It's not even funny anymore.

A preorder thread....


Im skeptical as most but its not that unlikely that the guy has ins with CNI and knows whats coming down the pipe soon. Its also reasonable that he does not divulge more source information if he is looking to sell these. We can get mad about this but its the same for most laser sources. I doubt Rayfoss or O-like will let you in on their sources either.
