LONG-WAVE INFRARED CAMERA AND CAMERA LENS HAVING 21-DEGREE HORIZONTAL ANGLE OF VIEW

摘要

The present invention relates to a long-wave infrared camera and camera lens having a 21-degree horizontal angle of view, the lens having a 21-degree horizontal angle of view being made of moldable optical material and having a concave surface (R2) for primary bending of incoming light from a subject, and a convex surface (R3) for secondary bending of the light that has passed through the concave surface (R2), wherein the concave surface (R2) and convex surface (R3) are defined by the relationships in formula 1, table 1 and table 2 of the detailed description.
