470nm diode

Ok, yes, Cryaragon

I bet you're proud of that, aren't you? The fact is: it's not clever, it's infantile.

you could assume that the laser manufacturer is just guessing about the frequency of their own lasers.

It wouldn't be the first time. The Chinese get wavelengths wrong all the time.

I guess you could also assume that I am making this whole thing up for... attention?

Don't be so defensive. No one claimed or even implied anything of the sort.

... If that is the case than I expect I'll be issued a refund in the next couple of days, and I'll be sure to tell you guys so you can rub it in...

Calm down. This is out of your control. Either it is, or it isn't. There's no one here to blame one way or the other. In fact, I think I speak for everyone when I say we appreciate that you're looking into it. We are simply voicing our skepticism - not towards you, but towards the claims.

It would be great if it were true, but if it's not, no one will lose any sleep, and I will be the first to jump on anyone that "rubs it in."
 
I'm sorry I snapped at people. Cyparagon, I have been trying to think of something I could call you that wouldn't require 20 seconds of careful copying every time I address you by name. Obviously Cry is too offensive to you. I tried Crypt, but rht wasn't digging it. If I called you C- would that make the grade?

I received a diffraction grating based spectrometer in the mail today. I did a reading on my 527nm green and got 525nm. I also read my 635nm red and got 645nm, so I think there's a slight problem with the scale they gave me being linear rather than quadratic. Regardless (I hope it makes you feel better that I spelled it without an "I", C-) I believe it will be sufficient to test whether the 470nm is approximately 470nm.

I wasn't digging "Crypt", because that's not correct letter order. I'm sure "Cyp" would be fine? Though "rht" isn't ;)

527nm? Do you mean 532?

The 635 could very well have been lasing at 645 though.
 
Yes, I do mean 532. :thinking: This thing is not terribly accurate. Well, I only paid $20 for it.

Lets see. 532 is 7nm above my reading of 525. 635 is 10nm below my reading of 645. All in all it seems generous to attribute a margin for error of only 10nm to my spectrometer.

"Cyp" is unpronounceable without adding an r or some other letter.

^ I think you should get your money back for that thing. :huh:

Btw, I pronounce Cyparagon: sigh pair a gone

how about aryntha? I met him at SELEM and forgot to ask how he pronounces it.

Get well soon M.T.

You still haven't explained who your supplier is ;p
 
The truth is that I have a product that I am trying to launch, and that I badly need to succeed. As an independent developer it is very hard to compete with the big boys. I feel that the name of my supplier is one of the very few assets available to me. While I wouldn't mind sharing my information with you and the other laser hobbyists here, I know this forum is not just read by laser hobbyists.

If my situation changes or if I end up abandoning my dreams I will be sure to let you know the identity of my supplier and how you can contact him. Until then I must decline to answer your question.

I've enjoyed your posts, and I think you have a good genuine interest in this subject matter - but I've got to call BS - again.

Not on you, on your supplier. I think they're taking you for a ride. I don't think they have any clue what they're doing, and I don't think anything they've told you about their proficiency or level of involvement in the laser manufacture process is true.

They suggested selling you a "UV" filter for your laser modules? These guys don't know what they're doing, they're probably not making their own modules, and I doubt that they are any more of a "supplier" than any other of a thousand chinese laser pushers.

I'll tell you what - don't tell me who your supplier is for now, but PM me with some of the prices that they've been giving you. If those prices aren't really an asset after all (ie, if I can give you better cheaper alternatives), then will you reveal your "supplier" so that we can all evaluate their credibility in the industry and dispose of this 470nm issue once and for all?

I admit that they are a little confusing sometimes. I will send you my list.

Honestly, in my experience this sort of thing is par for the course when dealing with wholesalers, even those who speak English fluently.

You know, for a second I considered telling you that my source for the inaccurate cheap spectrometer was ebay, but we both know that that would just be dodging the question.

You mean to say that your supplier in only making these diodes available to you? You fail/then they fail??

Yes the forum is read by others than laser hobbists, the big boys as you say, the Feds, and those in the business as they say, would already know about developments of diodes like this and such. Not saying who the supplier is because you want to sell them on here exclusively I can sort of understand that and you don't need to mention your project. I'm plenty sure "your" supplier is letting the industry know about these IF they can really deliver on them.

Good luck with your project, I hope you do succeed.......who knows maybe you'll even come up with something I'd like to buy myself :yh:
 
Well, I'm sure that if this is real then it won't be long until you start seeing this diode for sale in other places. If I had an agreement to exclusive access I wouldn't need to protect the identity of my supply lines. I fully understand where you are coming from, and I am sorry if my behavior offends you. I am only doing what I feel in necessary to have a chance of success.
 
Hey,

Quick update. I'm obviously not going to share any of the info you PM'd me (the prices etc).

But for everyone else's benefit - the nutshell is that all of the prices are actually pretty high. They can be undercut with even just a combination of DealExtreme and eBay. In most cases, the supplier's prices are ~30% or more above a DX / eBay option, and don't include free shipping (and also incur a bank charge)
 
Well there you have it: An independent audit.

I might add that price is not my only concern. The module is durable, is relatively compact, and looks good, and I can request changes to the design if need be. I used the cheapest option in town for my last design, and on those something would break or go out every night. These already have a 10x better track record, and with further refinement I am hoping to improve that even more.

Thank you for your review rhd.
