Chinese Fluorite transmission spectrum

The visible and NIR transmission spectrum of a path of approximately 3cm through a blue-green fluorite crystal from China. This shows a possible detection of a very small amount of water in the crystal: an equivalent depth of <3µm of liquid - by comparison with the standard water transmission spectrum (Segelstein - broad blue band).
