Abstract: This paper deals with the design of an optical system for a far-infrared camera for night object recognition for driver’s safe driving assistance of an intelligent vehicle. It was designed by considering the specification and mass production required for night vision of automobile. We designed the far-infrared optical system applying germanium optical system with 3 spherical configuration by using OSLO which is a special program for optical design. An optical system for a far-infrared ray camera with a wavelength band of 8~13[µm] was designed by applying germanium, which is a high-refractive index special material, so that the image can be realized by sensing radiant energy emitted by the subject. The designed optical system showed a total track length(TTL) of 35[㎜], a focal length of 15.93[㎜] and a horizontal angle of view of 26°. We have designed optical system for far-infrared ray camera with 3 spherical surfaces using germanium. We made optical design considering the mass production and miniaturization when manufacturing optical system. In addition to night vision systems for automobiles, it can spread to various fields such as crime prevention, fault diagnosis of high-voltage electric wires, body heat analysis and building insulation measurement.
