Weboptical image, the apparent reproduction of an object, formed by a lens or mirror system from reflected, refracted, or diffracted light waves. There are two kinds of images, real and virtual. In a real image the light rays actually are brought to a focus at the image position, and the real image may be made visible on a screen—e.g., a sheet of paper—whereas a … WebAn optical instrument called an endoscope is used for viewing inside the body.

WebFeb 1, 2004 · An optical system functions properly only as long as the optics remain within allowed tolerances of their nominal locations and orientations, and structural deflections caused by gravity and other external forces or by temperature changes do not excessively distort the optical surfaces. WebA lens is a transparent device with two curved surfaces, usually made of glass or plastic, that uses refraction to form an image of an object. Mirrors, which have curved surfaces designed to reflect rays, also form images. A system of lenses and/or mirrors forms an image by gathering rays from an object and then causes them to converge or diverge.
