PROBLEM TO BE SOLVED: To provide a single-axis lens module for a thermal imaging camera. SOLUTION: The lens module includes an object lens facing an object, receiving a light from the object to capture an image, and transmitting visible rays and far-infrared rays through one axis to integrate them; a beam splitter, located behind the object lens along the direction of the optical axis, reflecting the far-infrared rays from light which passes through the objective lens, and transmitting visible rays from the light; a far-infrared imaging lens located in the direction of the optical axis of the far infrared rays reflected from the beam splitter, receiving the far-infrared rays which pass through the beam splitter to form an image on a far-infrared detector which converts an optical image into a thermal image signal and outputs it; and a visible-light imaging lens located behind the beam splitter, by being located in the direction of the optical axis of the visible rays which pass through the beam splitter, receiving the visible rays, which are transmitted through the beam splitter, so as to form an image on a CCD sensor which converts an optical image into an actual image signal and outputs it.
