Awesome find! Doesn't surprise me though, 405nm causes tons of things to fluoresce, even peanut butter, it really is an interesting wavelength.

I work in DC, I can easily stroll through the Natural History Museum during lunch. Its crossed my mind more than one time to bring a small low powered 405 in with me to see what fluoresces in the gem and mineral section. Id love to see the Hope diamond "in a different light". Won't do it for several reasons though. I can already see the headlines, "Man charged with trying to destroy a national treasure" Lol! Don't need any more reasons to give the hobby a bad name!

Man, I have spent days in the Natural History Museum of the Smithsonian. On at least four different years. I have spent hours looking at the Hope diamond and wondered if it was the stolen French Blue. I used to live there. :crackup:

Yeah, it's a place that everyone who possesses a curious mind should visit at least once. Unbelievable, first-class collection of almost every natural curiosity. I especially like the meteorite section, the iron meteorites fascinate me being that they originated from the precipitated cores of planetesimals large enough for one have one form. Must have been one hell of a collision to break up something large enough to have an iron core!!!

Also, I highly recommend the air and space museum annex by Dulles airport(Udvar Hazy)sp?? as well. If you're even remotely interested in aviation/aerospace its a must.

Welcome back, jmgallego, been a long time since I've seen that cool avatar! :beer:

Len, you need to keep working on getting Autum to join us here. :yh:

Thanks BowtieGuy... I am trying to get back. Our friend Len is doing a great job in encouraging me to get do so. He sent me nice and detailed updates so I can quickly catch up with what is going here, it has helped a lot.

I just need to get my gears going and see what goodies are now at our disposal to play with!

:thanks:

:crackup: And I can see your photo with the details: "This evil man was inspired by laser technology used on sharks..."

That's great, jmgallego. All sorts of new diodes and assemblies out there. Very happy to have you back. I've been working on some new wavelengths in the 502nm to 510nm, 473nm to 480nm and the 495nm ranges. Have cataloged many diodes for future use. Got some beautiful blues out there now. :yh:

Lol! I'm a little late to reply but yeah, even though no harm would be done it would be front page news, seriously!

I've actually worked in the vault that contains the Declaration of Independence, Constitution, and Bill of Rights. Compared to minerals those documents can easily be damaged by some crazy with a handheld device. They are kept in an inert argon atmosphere so they wouldn't ignite but someone could easily add their John Hancock to the documents. I imagine it's just a matter of time.
