Overhead projectors are devices that project enlarged images on a screen. The system uses a mechanism that has a focusing lens to project a white light from an illuminated slide. Placing a mirror after or before the focusing lens will reverse the projected image. It displays the image that is present on the slide. You can place the overhead projectors at a height or at a distance for the light to reflect on the screen. Read through our blog to know everything about mini projectors.
