1. Lit. [of an image] seen clearly and sharply. (*Typically: be ~; come [into] ~; get [into] ~; get something [into] ~.) I have the slide in focus and can see the bacteria clearly.
2. Lit. [for optics, such as lenses, or an optical device, such as a microscope] to be aligned to allow something to be seen clearly and sharply. I've adjusted the telescope; Mars is now in focus.
