Morphology
The adjective 'anastigmatic' denotes the optical property (correcting or free from astigmatism) and when combined with 'lens' the phrase literally denotes a lens with that property. This is a straightforward, compositional combination (adjective + noun), so a learner who knows both constituents can predict the meaning.
Etymology
Anastigmatic lens names a lens made to remove astigmatism, a problem where points of light become 'streaks' or 'blur' instead of a clear point. So an anastigmatic lens gives 'sharp' images across the whole picture.
