<P>PROBLEM TO BE SOLVED: To provide an inexpensive optical unit which is used in an infrared wavelength region and can reduce a size of an apparatus, and an infrared imaging sensor. <P>SOLUTION: An optical unit 1 has a plurality of optical elements including a lens, and forms an image of light in an infrared wavelength region. The optical unit 1 comprises: an object-side lens 2 which is disposed on an object side and selectively transmits infrared radiation; an imaging-side lens 6 which is disposed on an imaging side and selectively transmits infrared radiation; and a metallic reflecting mirror 3 which refracts an optical path of the infrared radiation transmitted by the object-side lens 2 and makes the infrared radiation incident on the imaging-side lens 6. <P>COPYRIGHT: (C)2012,JPO&INPIT |
