Morphology
apochromat = apochromatic (semi-transparent) = apo + chromat
Derived via the adjective 'apochromatic' (apo- + chromatic) and then shortened or reanalysed as a noun for a lens; the morphemes point to colour-related correction but the noun sense is specialized.
Etymology
Apochromat comes from the Greek parts apo- 'away' and chroma 'color'. As a lens, an apochromat 'takes color away' from mistakes by bringing three main colors to the same point, which reduces colored edges and makes pictures clearer.
