<P>PROBLEM TO BE SOLVED: To provide a novel and improved imaging optical system for far-infrared rays which keeps a balance between cost and size, and an imaging apparatus including the imaging optical system. <P>SOLUTION: An imaging optical system that forms an image of far-infrared rays emitted from a subject on an image plane, includes a transmissive optical element refracting and transmitting the far-infrared rays and a reflection optical element reflecting the far-infrared rays on a surface reflection plane. <P>COPYRIGHT: (C)2013,JPO&INPIT |
