Morphology

slit + lamp

The noun compound 'slit lamp' is directly compositional: 'slit' (narrow opening/beam) + 'lamp' (light source) clearly yields a lamp that produces a narrow beam of light. Although it names a specific medical instrument, its basic function is inferable from the constituents and similar constructions occur cross-linguistically, so a B1 learner who knows both words can understand the meaning.

Etymology

Slit lamp comes from how the tool works: it is a lamp that makes a thin slit of light, a 'narrow beam' that shines into the eye. So doctors use a slit lamp to 'look inside the eye', which is why the name fits.
