reticle Fine lines or webs in the focal plane of an eyepiece, used for centring objects when guiding or for making angular measurements; also known as a graticule. The word implies a net or grid, but in practice a reticle may be a simple cross-wire or a series of concentric circles. The lines or the field of view are often illuminated.

ret·i·cle / ˈretikəl/ • n. a series of fine lines or fibers in the eyepiece of an optical device, such as a telescope or microscope, or on the screen of an oscilloscope, used as a measuring scale or an aid in locating objects.
