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 of 18x18cm (7,1x7,1") or 24x24cm (9,4x9,4").
