Morphology

This is a regular suffixal formation from the verb 'focus' with '-er', meaning a person or device that focuses.

Etymology

Focuser comes from focus, an old Latin word meaning 'hearth' or 'fireplace', a warm center where people and attention gather. So a focuser is someone or something that brings things to the center or makes an image or idea clear, like a lens that makes a picture sharp.
