Epidiascope

epidiascope

[‚ep·ə′dī·ə‚skōp] (optics) An optical projection system for forming an enlarged real image of a flat opaque object, in which light is reflected from the object and then from a mirror before being focused by a projection lens. Also known as episcope. An optical projection system which can easily be altered to project either transparent or opaque objects.

Epidiascope

a device for forming an image of an opaque object on a screen as well as for projecting a transparent image, or diapositive, of an object onto a screen. An epidiascope is a projector whose optical system consists of a combination of an episcope and a diascope (see Figure 1).

In diascopic projection, the diapositive is illuminated by a light beam directed through it; thus, the image formed on the screen is sufficiently bright even with a weak light source and projection lenses with low transmission characteristics. Episcopic projection requires the use of light sources that are more powerful and high-transmission lenses.

epidiascope

ep·i·di·a·scope

(ep'i-dī'ă-skōp), A projector by which images are reflected by a mirror through a lens, or lenses, onto a screen, using reflected light for opaque objects and transmitted light for translucent or transparent ones. Synonym(s): overhead projector [epi- + G. dia, through, + skopeō, to view]

epidiascope

A projector used to project by reflection opaque pictures (such as the page of a book) onto a screen.
