WebA Lyot [1] stop (also called a glare stop) is an optical stop, invented by French astronomer Bernard Lyot, that reduces the amount of flare caused by diffraction of other stops and baffles in optical systems . Lyot stops are located at images of the system's entrance pupil and have a diameter slightly smaller than the pupil's image.
