Morphology

absorption + unit

The phrase is a straightforward noun–noun compound where 'absorption' (the process of taking up energy/substance) combined with 'unit' (a measurement standard) yields the meaning 'a measure for absorption.' This compositional pattern is literal and cross-linguistically common, so a B1 learner who knows both constituents should be able to infer the MWE meaning.

Etymology

Absorption unit comes from the simple image of a material 'soaking up' light like a sponge. Here absorption is the soaking and a unit is a small measure, so an absorption unit is a simple way to say 'how much light a sample absorbs'.
