1x AAA host Rainbow

[qumefox]

This is a set I've been collecting parts for for a while, and finally built while I was sorting/cleaning/getting rid of stuff in preparation for moving.

The hosts are stainless steel trustfire xp-e f23's that I turned down in the lathe.

They run off of 1x 10440, except for the 532nm, which uses a 10280.

The wavelengths are 401nm, 413.5nm, 445nm, 512nm, 532nm, 637.5nm, 658.5nm.

A little more info on the 401nm and 413.5nm please

Wow, those do looks pretty nice.

All you need to complete it is to add a nice little yellow in the middle

 

[qumefox]

The 401 and 414 are nothing special..

Step 1) buy a bunch of 405nm diodes.
Step 2) buy a spectrometer
Step 3) Test all of said 405nm diodes and keep the highest and lowest you find.

As far as yellow. I MIGHT could cram a 593.5nm module in one of these hosts.. MAYBE.. I managed it with 532 after all. But.. I don't have $400 to throw at laser stuff at the moment to buy a GPL-593.5 pen.. especially not to cut up for the module.

 

[Zeebit]

414 is pretty far from 405 and its a lovely color. What current are the two running at?

 

[ARG]

Nice build, I have always wanted to make a matching set.

Visually does the 401 and 414 appear any different?

 

[qumefox]

Both the 401 and 414 are running at 100mA.. the 401 is 55mW, the 413 is 52mW

And yes, 401 and 414 are visually different.. Both normally and in the fluorescence they cause.. the 401 has a significantly greater effect on UV reactive materials than the 414 does.

And yes, I know 414nm is high, but in the past, it wasn't that uncommon for diode datasheets to spec +/-10nm since they production diodes could vary that much after they were initially developed. And my 414 is likely an old diode. New diodes, at least going by nichia datasheets, seem to be +/-5nm though.. But they've also been making them for almost a decade now as well. I'm sure their manufacturing practices have improved and tolerances have decreased. That or they just bin them now. Nichia does have part numbers for 415nm diodes now after all, as well as pretty much everything else between 380nm and 520nm.

My point being though.. I didn't do anything special to get that diode. It's either out of a PHR-803t, a 12x, or an ebay newwish "5mw" 405nm pen.. Because those are the only 405's i've ever bought.

Stainless steel uniformity, wavelengths changeableness. Hot looking shiny rainbow set in pen style you've got there, sir:beer:. Like it!

 

[Photonz]

Awesome set you have there the 414 looks amazing and definitely stands out.

 

[ped]

They are superb hosts. Well done.

 

[Atomicrox]

Fantastic!

Since you have a spectro you should consider trying to bin a high 450nm. My Dominator is at about 454nm (wall-spectro-eyeballed on a ruler) and it's a much different color from usual 445nm.

 

[Pman]

I really appreciate the smaller pen style units and this is just a great grouping here. Such a nice elegant set. +REP
Sure wish I had a spectrometer now. I've got so many units (somewhere over 250) that it would be fascinating to test them all to see what I really have. Unfortunately none of them seem to have morphed into the 589nm region
By the way, why is it that I can't add anything more to my Sig when some people seem to have so much more down than I do? Sorry if a bit off topic but I figure there's a quick answer.

 

[ZRaffleticket]

Hm... This makes me want to get two 405's with big wavelength differences... hm... awesome builds!

@pman - Change your links to tinyurl's, it saves a lot of space. (Character count determines sig, not length)

 

[Atomicrox]

Pman, perhaps you can get someone with a spectro to lend it to you in exchange for a nicely binned pen? With that sheer amount you ought to have one down on the UV range!

 

[Tmack]

Wow very nice . I've just ordered a handful of sinners pens for a smaller rainbow myself.

 

[qumefox]

It's funny. The one that I consider the most special is one thats 'common' now apparently. th 512nm. It was diode #3 of the direct greens that were available to the hobbyist community. RHD and Aryntha had the first two.. I sat on this diode forever because frankly.. I was scared of doing the build. Though it's not quite as low in wavelength as i'd hoped it'd be. I was hoping it'd be below 510nm.

And Pman, you don't really need a spectrometer. Unlike the high reds, it's not hard to spot a 10nm shift down in the violets, Especially if they're the same powers. Say, if they're all newwish pens for example. If that's the case, sort them by power using an LPM, lay them out lowest power to highest and point them at the same non fluorescing surface and turn them all on. If you have a high one or low.. It won't be hard to spot, trust me. In this range, the higher wavelengths will appear a lot brighter than the lower ones. For instance my 55mw 401nm only has about 20% the brightness, dot wise, as the 52mw 414nm. Actually when I was testing my diode collection I knew this particular diode was a lot brighter than it should have been even before getting the spectrometer out.
