Several times KT has posted SW 254nm pictures and noted that there were 3 SW lamps set up to take the image. He thought perhaps since His Majesty only has 2 Royal hands, you might wonder how that is done and KT still be able to take the image. The first 4 pictures show how it is done.
Picture 1 shows what was used to make a hanger for one of the lamps to be on the Royal tripod....
Picture 2 shows the position of the hanger on the tripod with the lamp hanging from it and where the camera mounts and the photo blackout box. Picture 3 shows the how the hanger is holding the lamp. And picture 4 shows how the other 2 SW lamps are set up when KT takes a picture. His Majesty thought this might interest someone.
Picture 5 shows a natural light image of another calcite marble specimen from Long Lake Zn Mine, Ont., Canada. US dime in all pictures for scale. Note that in natural light no other mineralization can be spotted. Picture 6 shows the same specimen in the SW 254nm light from the 3 lights positioned as shown in picture 4. Note that Chondrodite fluoresces a nice yellow and the calcite matrix is pastel red.
In Picture 6, taken in LW 365, chondrodite does not fluoresce, so the Diopside response is now visible, along with red responsive calcite. Just goes to show you always need to check with both LW and SW to get the more complete story! The specimen was sold with no mention of diopside on the specimen and no LW image provided.
Anyway, enjoy the pictures!
