the difference isnt that strong as with the red sticker. the 405-->blue conversion is quite effective, and both dont look that much different.
but hey, anyway: "look ma, a 50$ blue laserpointer!"
the conversion to green is so strong and complete, you dont see much difference on the pics. in nature you see it more pronounced though. hint: take your 405nm laser and googles to the next fleamarked, and shine it (without blinding others! reflections!) onto green glassware. if it shines, its uraniumglass, old, and (relatively) expensive! have a look at ebay for prices! ..now guess where and how i got that nice bottle.. ;-)
i got me green fluorescening string to do some "string-art" like at some goa-parties. man, this stuff shines green! nice for blacklight-tubes, for sure!
again, no big difference on pics. most of you will know how strange some digicams behave with 405nm, in either way.. here, with bright lights (as with this one, or with paper) it simply oversaturates the cam, and looks more like white. you dont see the leftover 405nm light (on the last pic). so, again, the effect is more visible by eye.
at least you can see how little fluorescence there is, once you use the googles. with the naked eye you see the security-stripes, on this pic you (can not) see a red one.
interesting effect: to the naked eye, it looks blue, like paper. with a filter, it actually looks white! i believe i bought it as "blue fluorescening", though. the regular color of this stuff is white, too.
who would have guessed? chlorophyll shines deep and intensive red! green leaves have different parts, the underside shines red much less, the harder middle-"lines" dont shine red at all. different places of the plant shine different. and all that although it all looks the same green! i have to check in fall, when plants take the clorophyll out of leaves!
they shine different intensities of red, some more, some less. but all do shine!
i found them at a place with quartz-crystals. i really did separate them later with that laser, it wasnt even possible by naked eye!
hey, perhaps this was the first time i really *used* a laser? this, or the laser-waterlevel. no, wait, it didnt help when i tried
