Default Re: 505nm and 480nm diode RESULTS

I got my 473nm diode today and it has quite a bit more green than I expected it has to be at least 480nm if not higher! Sadly I don't have a good camera to truly capture the color. To me this is the closest thing I have found to the color. Imgur: The most awesome images on the Internet

Default Re: 505nm and 480nm diode RESULTS

Welp, it took USPS 4 days to ship from washington state to pennsylvania. They were supposed to arrive at my house yesterday... They just left the closest sort facility to me at 4am... So I won't have them today. I might tomorrow, but that would mean I can't send them out until Monday. If they make it tomorrow.

If they don't arrive until Monday, I won't be able to send them out until the following Saturday as I will be away from home for work. Fun.





@billybob you might've gotten real lucky with a freak diode. I'm just glad I got one coming that actually hits 480nm on the mark.

@Rich did you get that one spectro'd?

Default Re: 505nm and 480nm diode RESULTS

This is one of my ~473nm Diodes @100mA, ill try and get some decent beam shots with my camera soon.


And a 505nm i have @100mA.
532nm next to this looks Bright Yellow, crazy how the eyes adjust to the colour spectrum.

Default Re: 505nm and 480nm diode RESULTS

Gotta love USPS... I have a package that should be arriving today that came from Arkansas>Alabama with a nice detour to Cincinnati Ohio.. How they manage some of this, I will never know. Tempted to start a thread titled "Mail horror stories" about crazy late/lost packages. Went from "USPS Awaiting item" to "Accepted at USPS Origin Facility : CINCINNATI, OH"

Hopefully that package makes it's way to you promptly. Probably got thrown off due to the 4th closing down anything gov't related.
On second thought, if those don't promptly make it to you, want me to ship you a box of lead with signature confirmation? Would offer to send a brick of osmium but I don't have a few hundred thousand dollars laying around... any sponsors?

Default Re: 505nm and 480nm diode RESULTS

Hi Z,
No i didn't get it spectoed but i purchased them with the 505's at the same time so I'm assuming but still happy with the WL . I may build one into a full copper pen have some copper round stock coming in today so i have to get my measurements in order and make a prototype . It will take 1- 10440 cells for the single modes and later down the line 2- 10440 cells for the 5.6mm multi's .

Default Re: 505nm and 480nm diode RESULTS

Looks like the ebay listings posted a picture of the diode face. Although all three listings are using the same picture, and uploaded them around 10 minutes apart.
Also, I bought one from Newgazer, So when it arrives I'll spectro it.

I wonder how many of the true 505nm diodes are out there?

Unless you have access to a spectrometer, you can't KNOW what the wavelength of that diode is. They do look differently to many people and cameras alike. I have spec'd ten of these diodes and none of them were higher than 480nm.


ZRaffleticket, I sent those out last Monday and was told you would receive them by yesterday. I checked the trackng on them and it looks like they might be out for delivery today. Just in case, be on the look out.

Default Re: 505nm and 480nm diode RESULTS

So i sent an email to the Ebay seller Newgazer who also got a batch of these 505nm diodes, asking for a photo of the face, and "drum roll" guess what the result is......

Yep, SB1573N91

The photo in the listing clearly shows an SB1573N91 number and not the SB1473N91. I wonder if there are three iterations of this so called 505nm diode.

So we have:
-SB147EC91 closer to 510nm? (DTR, Song, ZRaffleticket, Lazerman121 second batch)
-SB1473N91 505nm diodes. (Lazerman121 first batch)
-SB1497N91 505nm (Lifetime17)
-SB1573N91 which may be 505nm if Dr.Laser's diode is representative. (Newgazer)



I ordered one of the SB1573N91 and will spectro it when it arrives.

haha I think we need a compilation!

EDIT: @Mattronium, we are thinking alike

Yup it seems it made it to my post office through magic. Cool, diodes will be shipped out tomorrow morning guys. I'll pm you what they come out to when I'm home.

Also, if you can confirm <505nm on those diodes -- ooohhhhh

Now I am confused. Did someone that got one from the batch I have or got one from this Song person that had the same number as the ones I have test it? If so I missed it. I thought the only tests so far were on the

SB1473N91

and

SB147EC19

The batch I have

SB147EC91

I was going off this post on what has actually been tested so far.

Default Re: 505nm and 480nm diode RESULTS

I believe the SB147EC19 number was during a dyslexic period laserman121 was having and does not, nor never existed. I believe he meant to say SB147EC91. Until the photo showing the SB1573N91, I believed the two former numbers SB1473N91 and SB147EC91 were the only ones we had. I'm not even sure the SB15 number relates to these diodes at all.

The ones ZRaffleticket had were always the SB147EC91 diodes.

That would make more sense then. What was the wavelengths @ 125mA on the C91's that were tested?
