August 22, 2008, Newsletter Issue #133: What is an Opaque Projector?

Tip of the Week

An opaque projector is similar to overhead projectors used in classrooms throughout the country. Because opaque projectors reflect light they must use brighter and larger light bulbs than a normal overhead projector. An opaque projector takes an opaque object and through a system of internal prisms and mirrors, the object that is set under the opaque projector for viewing is shown enlarged onto a screen, a wall or an easel for easy tracing.
