Overhead Projectors
Tips & Advice to help you make your decision on Overhead Projectors
Overhead projectors are one tool a person can use to give a presentation. They use the mechanics of light, lens and mirror configuration to pick up data contained on a transparency and display it on a wall or projection screen for viewing by many people at one time. The data or image is first copied onto a transparent film that is placed over a light box. Above the light is a lens that captures the light and the image. Above that is a mirror and another lens which directs the light and the image forward, creating the projection.
Projectors are not used as often since the creation of computer presentation software and hardware but can still be useful. Seminars and training classes often use this method for displaying information for students during a lecture. Other uses are to display business data, charts and graphs during meetings. Though somewhat bulky, they can be transported so that presentations can be given anywhere.
To purchase overhead projectors requires a little knowledge about the product and where to find vendors. Finding replacement parts can also be tricky as not many companies still make these devices. A quick search of the web may not yield the most desirable results but Business.com can provide the links you need to find suppliers of equipment and parts.
