Diffraction-limited system

In optics, any optical instrument or system—a microscope, telescope, or camera—has a principal limit to its resolution due to the physics of diffraction. An optical instrument is said to be diffraction-limited if it has reached this limit of resolution performance. Other factors may affect an optical system's performance, such as lens imperfections or…
