Morphology
stigmatism = stigma (opaque) = stigmat + ism
Although formally built from the morpheme 'stigma' + '-ism', the optical sense ('correct focusing') is specialized and not derivable by a typical learner from the everyday meaning of 'stigma'.
Etymology
Stigmatism comes from the Greek root stigma meaning 'mark' or 'point', and in lens work it became the idea of all light rays meeting at one clear 'point'. So, stigmatism means an optical system that focuses light correctly to give a sharp image.
