Scheelite, Italy - fluorescence and transmission

404nm 532nm 254nm excitation (green, red and blue lines respectively - shifted vertically by 10 flux units).
Note the absorption complex in the transmission spectrum between 520 and 540nm. This absorbs the 532nm laser light to excite the strong REE fluorescence around 900nm. It also excites weak fluorescence at 890nm in the transmission spectrum itself.
