wait till you see the rest of the rainbow!!!!
your seeing ball would pop from just looking at the photo(even with safety goggle).

Lol! I really like the last picture. Did you put the 503 into a handheld or is it just my eyes tricking me?!?!

Re: Rare Wavelength from Cytometry Machine Update!!! Photo Added!!! and More coming.

Would like to know the make and model number of the machine like others. Great find.
 
Re: Rare Wavelength from Cytometry Machine Update!!! Photo Added!!! and More coming.

Seconded, we need a model number..
Was the diode press fit in somewhere, or what? How did you know what current to run it at, and what driver are you using?

Cool. I almost got one of these a while back. It's probably one of the nichia emerald diodes. So you're probably running about 506nm. I can spectrometer it if you wish.

This^

What are you running the diode with, at what current?

Holy crap the pictures are unbelievable. 503nm handheld, at THAT high power level the beam is so sharply visible is something new.

Can anybody grab some info on availability and pricing of such diodes?
 
Re: Rare Wavelength from Cytometry Machine Update!!! Photo Added!!! and More coming.

They're preliminary they're not intended to be used in products just yet for the most part. I actually had a small batch of 504 diodes a while back for testing. They have a habit of climbing up to about 506nm unless they're TEC cooled, and run at very low currents. Usually 100mA or less if you want 504. They like it cold A simple handheld heatsink isn't optimal but will certainly allow it to run comfortably it'll just go a bit extra green.

Power technologies actually makes modules with them that are fully centered at about $1000

I don't care about precise wavelength, 503 or 506, plus minus 3nm : meh.

Point is, as you provided some availability info, OP is currently the only one with 503nm diode handheld and judging from the situation, will be for quite some time? You haven't assembled any yourself? What's the output power of the diodes you had over for testing?

That's just... wow. Bit out of the blue.
Maximum respect to the FUBeaches.

And not to mention there's more diodes in there as far as we can tell from his posts.
 
Re: Rare Wavelength from Cytometry Machine Update!!! Photo Added!!! and More coming.

Indeed. Getting cytometers apart is very fun but a pain in the ass.

The two I had were screwed into small 5V modules with beam elliptic corrections and are designed to run 504 at around 100mA iirc around 35mW. I'll have to go dig up my notes on them, I'm at work right now. I do remember that I was able to get one down to about 502-503 using a very cold TEC. And believe me a few nanometers down here make a big difference, much like the yellow range. 503 and 508 ish are like night and day. At least to me. 502 is much more blue where at the max it's closer to 508 with the thing pretty cold and is much more green.

Nichia has had them for a while. I'm sure they have a spec sheet online. They specified running it in test at some 20 degrees C. They have 100mW 473 diodes and I think a 1.2W 473 is in the works.

473nm diodes would be great, as long as they don't cost an arm, a leg, a kidney and a firstborn.

Damn I'm out of the loop. Link to 100mW 473nm availability and pricing?
 
Re: Rare Wavelength from Cytometry Machine Update!!! Photo Added!!! and More coming.

They are a few grand. Lol

The things I'd do with infinite money...



...buy a cytometry machine, probably. :D

Until then, 2W 462nm diode from DTR's look interesting.
 
Re: Rare Wavelength from Cytometry Machine Update!!! Photo Added!!! and More coming.

Meh. Dpss 473 is far superior for most applications and still cheaper. So I don't care much. The superior beam profile and narrow line width of DPSS are far better to have in my opinion than saving a tiny bit of space and power though the modulation times are slight better with bare diodes I think, but I could be mistaken.

I'd love to have a 500.8nm labby. That's my favorite dpss WL I think.
 
Re: Rare Wavelength from Cytometry Machine Update!!! Photo Added!!! and More coming.

Nevermind I think the 503nm statement is a typo on the PT web page.

I think so as well.. I did a quick search on google and here as well and came up with nothing.. very lucky find need I say how beautiful that wave length is haha:beer:
 
Re: Rare Wavelength from Cytometry Machine Update!!! Photo Added!!! and More coming.

Yeah this is in the area of my favorite wavelengths I love the cyan area 488-500 ish. I filed an inquiry with nichia. I'll see how much a unit or tray costs. Might be a possible GB option if they're not too expensive. Depends on which emitter is involved.

I'm kind of happy to see that these are finally trickling down into equipment
