Large format lenses are photographic optics that provide an image circle large enough to cover the large format film or plates used in large format cameras.
Photographic optics generally project a circular image behind that is only required to have acceptable correction of aberrations over the intended film/sensor diagonal with little room to spare. Lenses that may be able to produce a considerably larger image circle than is needed (notably long focus lenses), but optimised for a given image format will typically mask this excess coverage off to minimize reflections and reduced contrast.
However, Some Medium and Large format cameras have movements, such as view cameras also sometimes known as technical cameras. Allowing the lens to be shifted and/or tilted from the sensor/film axis without vignetting in the corners opposite the movement requires a larger image circle. For this reason, large format lenses often produce image circles significantly larger than the film/sensor diagonal they are nominally aimed at
Compared to mainstream cameras that typically have non-interchangeable lenses and/or focal plane shutters operated from the camera body, another difference with medium and especially large format lenses is that they are typically interchangeable in a very simple manner, being mounted in a "lens board", and include a shutter just in front behind or usually in the middle of the lens. This shutter is tripped directly at the lens (possibly using a cable release), not by a release on the camera body
