Overhead projectors

Business owners often use overhead projectors to present ideas visually during presentations. Overhead projectors display images onto a screen via a bright lamp, a large fresnel lens, a smaller objective lens and a mirror. Although overhead projector designs vary by manufacturer, design elements shared across manufacturers can pose certain dangers to you and your audience.
