Need source for 425nm diode.

I am wondering if anyone has a source of single "low" priced N!CH!A NDV4A16E diodes.
I want to do a pen build with one sometime this year after I acquire my tax return laser but can't find any of these diodes anywhere or any information beyond the datasheet for them.

I vaguely recall seeing someone with a 425nm build in their sig but am unsure who's it was.
If that person or anyone else knows where the diode was acquired and even better yet at what price I would greatly appreciate this information.

Datasheet here:www.nichia.co.jp/specification/products/ld/NDV4A16E-E.pdf
I came across this browsing through N!CH!A's selection of diode in the visible spectrum hoping to find something truly unique but have yet to find a source.



EDIT:
I would also be interested in a reasonable source for N!CH!A NDE4116 diodes as this is another wavelength range I have a particular interest in as I can perceive very small changes in the green spectrum and this should fall right at the blue end of green.

The person who claimed to have such a diode was tomfire1735. He is now banned.
Seeing as he tried to scam me twice and claimed to have a 50mW 593.5nm portable, I would not trust him to wash his hands before making a sandwich.

If you do manage to find a source, however, I'm all in.

Im starting to wonder if this diode is sourcable at all.
Even ThorLabs doesn't list anything even close and the "E" in the part number is for "engineering sample"

Hopefully something comes through though as I imagine quite a few wavelength junkies might want to fill the ~405-~440 gap.
Or just want a higher visibility (per mW) violet-ish laser in their collection.
I am not going to give up my search as this is one of the few portable wavelengths I am looking to get that currently exist.

Thank you for that link Dr. Laser. Although I see their prices one some wavelengths are insane simply because the labs/uni's that would be interested in replacing dpss/gas with diodes tend to have deeper pockets.. like that 6000 USD 473 diode.

It would seem that for now the 425 region is not within my budget...

On a side note:
Is that 488 a CNI wavelength or a custom build using one of these unicorn diodes that may or may not exist?
I know styro has gotten a few direct diodes with dpss & argon blue wavelengths before..

I see you have a 488 GLP incoming from CNI in your signature? How much did that beauty cost you? :eek:

This 488nm build is a custom job done by CNI. I had to send them my own diode because they won't take risks experimenting something new plus it is much cheaper this way. The diode is Osram PLT5.

If nothing went wrong then I should have the completed build by the mid of this month. The total cost of this would be a little over $1000.
I'll certainly make a post about it once it arrives.
