Abstract
An efficient, precisely controlled apparatus for and method of heat fusing an image onto a receiver element, such as a slide transparency. The apparatus includes a light chamber which integrates and directs to an open end of the chamber light from an area light source which emits black body radiation at a given color temperature. A receiver element with an image to be fused is positioned adjacent to the open end of the chamber and the light source is turned and off by an electric timing and control circuit. The electric circuit precisely controls the color temperature of the light source. The circuit also electronically measures the temperature rise during fusing of the image to the receiver element then immediately turns off the light the instant complete fusing is accomplished. The method includes the steps of controlling the color temperature of the light source in accordance with optimum energy absorption by the image and by the surface of the receiver element, applying the light energy with a controlled intensity pattern to obtain highly uniform temperature rise over the area of the image including its edges, and measuring the rise in temperature produced by the light and turn…
