Morphology

optical + instrument

The meaning 'a device that uses lenses, mirrors, or other optical components' is directly derivable from combining 'optical' (relating to vision/light) with 'instrument' (a device or tool). This adjective + noun composition is a straightforward, cross-linguistically common pattern in English, so a B1 learner who knows both constituents will readily understand the MWE.

Etymology

The term optical instrument comes from the words optical (about 'seeing') and instrument (a tool). Imagine a tool with lenses or mirrors that makes distant things look close or small details clear, so that's why it means 'a device that helps you see'.
