Abstract
An overhead projector that irradiates light onto an object or a sheet of paper, focuses the light reflected therefrom with a focusing lens, isolates ultraviolet or infrared rays having a specific wavelength among the focused light via a filter, forms an image by irradiating the isolated light onto an image former, and projects the image onto a projection screen by irradiating visible light onto the image former whereby the image is enlarged and projected via a projection lens to thereby obtain a more clear image.
