| 摘要 |
The present invention relates to a high-resolution far-infrared optical system having a wide field of view. The present invention comprises a plurality of lenses, and each of the lenses forms an aspheric surface, thereby enabling minimizing of image distortion. Moreover, two or more of the lenses further form a diffraction pattern, thereby enabling minimizing of changes in the focal length in the temperature range from -40°C to 60°C. |
