Episcope

 

an optical system for projecting onto a screen images of opaque objects, such as hardware, technical drawings, illustrations, and photographs.

The basic optical diagram of an episcope is shown in Figure 2 in PROJECTOR. In an episcope, the object whose image is being projected reflects diffusely the light rays striking it; thus, only a small amount of the reflected light enters the projection lens. The brightness of the image is enhanced by using one or more powerful light sources as well as high-transmission projection lenses with relative apertures of up to 1:1.5–1:2. Since the focal lengths of episcope lenses are usually shorter than those of diascope lenses, the magnification produced by an episcope is lower. A mirror located above or behind the projection lens of an episcope inverts the image so that it is right side up when it appears on the screen (see: Figure 1). A special cooling system is required in an episcope because of the intense heat that is generated.

An episcope may be a component of the optical system of the alterable projectors known as epidiascopes, which can project images of both opaque and transparent objects onto a screen.

Episcope is a neologism derived from the Greek episcopus, which in the Christian Scriptures designates the leaders of Christian communities who come to exercise "oversight" variously through presiding, teaching, and shepherding, where shepherding is understood as a matter of discipline, including determining membership and participation in the community of faith.
