Sounds like a hard life.....only worry if you start baying.sand surfer said:Brumble-Gum said:I just read this.
Platypus fur fluoresces too!
Well bugger me Brumble-Gum ,if i am on the locos next year and go to a certain area, i might take the UV torch and have a look ,there is a creek we cross that has platypus in it, on full moon nights if i am out that way i park on the bridge and have crib and watch them play erfect:

I have always wondered why I glowed in the dark, always thought it was the clean living and being a really nice person was the reason, but looks like I was badly mistaken as I have been told by a lot of people. :lol: :lol: :lol:
You have gotten me curious now. These torches, where can they be purchased?BigWave said:I thought I'd start this to show interesting stuff fluorescing under UV lamps.
Not just minerals, but our currency has some great anti-counterfeit effects using UV lights:
Can you see the bird on our $5 notes (and check out my ciggy lighter handle):
Can you see the manufacture date and serial number:
Can you see scorpions in the bush at night? They glow like light houses at 10m using a Convoy S2+ UVA torch. They're everywhere in the Vic GT. In your tent?
Then check out ladies' UV nail polish, real rubies (glow a brilliant red - not fakes), diamonds (50% glow blue), lichens in rain forests - all sorts of colours.
Hundreds of other things glow when exposed to UV light that you can't see when only illuminated with visible light.
Tonic water glows faint blue, dog/cat piss (well - maybe you don't want to know - don't check your carpets or sofas where they sit).
Also, don't use a UV torch in your hotel room at night - particularly the dunny - well - you really really don't want to know.
No wonder these lights are used by forensics staff.
My reservation about any of these is that some fluorescent minerals won't fluoresce at their 365 nm wavelength. For example, 60% of opals fluoresce and UV can be used noodling, but that would not be likely to work with these (need short wave UV - must use goggles). Also I suspect that their intensity is poor (so I would go for the 6W version not the 4W, although still weak). I suspect filters may not be desirable because it would possibly reduce the UV further despite getting rid of much visible light. But good fun when starting out, and a relatively safe wavelength.BigWave said:Check the net for Convoy S2+ with the 365nm Nichia LED.
Dihusky said:It's all horses for courses, getting scientific is one thing, but a short wave torch is very handy when checking gem rough, night fossicking in old Tin mining dumps for Topaz, palming and running over a tray of Garnet rough to see if a Ruby has been missed or discovering the Rubies aren't. The list goes on...
For collectors and photographers of Fluorescent minerals higher grade lighting will be the go-to but difficult to carry in the field. Our little Convoys have found us some great material and it's a lot of fun discovering other things that fluoresce that you don't expect.
