Morphology

undilated = dilated (transparent) = un + dilate + ed

A straightforward negation: 'un-' + the adjective 'dilated' gives 'not widened', which is directly inferable.

Etymology

Undilated starts with un- meaning 'not' and the root dilate meaning 'to make wider'. So undilated literally means 'not widened', for example when pupils stay small and do not open to let in more light.
