摘要： The present invention relates to a far-infrared camera optical system and provides a far-infrared camera optical system comprising: a first lens as a meniscus lens, in which a first surface facing an object is convex towards the object, which has a positive refractive index, and of which both surfaces are aspherical; a second lens as a meniscus lens, in which a third surface facing the first lens is convex towards the first lens, which has a positive refractive index, and of which both surfaces are aspherical; and an infrared filter arranged at the rear portion of the second lens and passing only far infrared rays among incident rays, wherein the focal lengths of the first lens and the second lens satisfy [equation 1] and the dispersion ratios of the first lens and the second lens satisfy [equation 2]. The present invention can detect lives or things located at 1000 meters or more and be applied to various fields (night guard, crime prevention CCTVs or the like), and has a structure which can be formed by moldings, thereby simplifying the manufacturing thereof and reducing manufacturing costs.
