Abstract
In this paper following discussion the author concluded that the optical system for IR detecting in the distance should be an total reflecting off-axis aspheric system with large relative aperture and large field of view. A system with diameter φ600 mm, f=1000 mm, and linear field of view ± 5° was designed.
