Morphology

achromat = chromatic (semi-transparent) = a + chromat

Formally 'a-' (not) + 'chromatic' is clear, but the sense 'achromat' as an optical lens is a technical usage tied to optics and may not be obvious to average learners.

Etymology

The word achromat comes from Greek parts a- 'not' and chroma 'color', so it literally means 'without color' and refers to a lens that removes color errors to make a clearer image.
