Morphology
optical + flint
The element 'optical' clearly signals a relation to optics, and a learner who knows 'flint' as a material might infer this is some material used in optical devices, so there is a partial compositional cue. However, the specific sense — a particular high-dispersion, high-refractive-index type of glass — is technical and not directly predictable from the ordinary meaning of 'flint' (a rock), making full interpretation unlikely without prior exposure.
Etymology
The noun optical flint comes from an old type of glass called flint, named after the hard flint stones people who made glass used to make heavy, clear glass. The word optical shows it is the kind that bends light strongly and can 'split' colors, so the name helps you remember it is the special glass used in lenses and prisms to correct color problems.
