Or SLR. A type of camera that has a movable mirror behind the lens and a ground glass for viewing the image. Film sits behind the mirror assembly, which swings out of the way when an exposure is made. Single-lens distinguishes it from TLR, or twin-lens-reflex cameras, where separate lenses are used for viewing and taking.
