About: Large-format slide projector

An Entity of Type: Whole100003553, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

A large-format slide projector (also often called large-format projector or large-image projector) is a kind of slide projector for large image projection which has a very powerful light source (up to 12 thousand watts using arc lamps). Therefore, it is necessary to use a large slide format to protect the slide material from overheating during the projection process (even when the light is filtered to only visible light and the slide is cooled with strong slide cooling fans). Slide formats include 18 × 18 cm (7.1 × 7.1") or 24 × 24 cm (9.4 × 9.4").
