Though it doesn't deal with the measurement of transparent resins
specifically, there's a good summary of spectrophotometry in general
in

Johnston-Feller, R. (2001) Color Science in the Examination of
Museum Objects: Nondestructive Procedures (Tools for Conservation)

We've been using a portable spectrometer with integrating sphere
geometry (Konica Minolta CM2600d) to support accelerated
light-fading tests. We're looking at objects with polychrome
surfaces, and find it very useful. It works my measuring reflected
light though, so I wonder how successful it would be at measuring a
translucent material.
