54 Long-Wavelength Infrared Camera with 54 degree Angle of View and Lens for the Carera

摘要

An objective of the present invention is to provide a long-wavelength infrared camera having a horizontal angle of view of 54 angular degrees, capable of applying an optical material for mold forming, thus reducing manufacturing costs in comparison with the traditional germanium lens and easily being applied to civilian fields through mass production; and a lens for the same. According to the present invention, the lens for the camera is made of an optical material for mold forming, and comprises: a concave surface (R2) preliminarily refracting incident light from an object; and a convex surface (R3) secondarily refracting the light having passed through the concave surface (R2).
