Abstract: PURPOSE: An image optic system for monitoring inside of furnace is provided to reduce an installation cost by observing images of the inside of the furnace without additional devices. CONSTITUTION: An image optic system for monitoring inside of furnace includes a wide-angle lens group(1-3), a front lens group(4), an erect image lens(5), a rear lens group(6,7), and a screen(8). The wide-angle lens group(1-3) is used for processing the incident light from an opening portion of an incident portion. The wide-angle lens group(1-3) has a positive refractive index. The front lens group(4) is formed with an image transferring lens in order to transfer an image of the wide-angle lens group(1-3). The erect image lens(5) is used for converting the image of the front lens group to the erect image. The rear lens group(6,7) is formed with an image lens. The screen(8) is installed at the outside of the furnace.
