Overhead Projectors

An overhead projector typically consists of a large box containing a very bright lamp and a fan to cool it. On top of the box is a large Fresnel lens that collimates the light. Above the box, typically on a long arm, is a mirror and lens that focuses and redirects the light forward instead of up.
