Abstract

An optical radiation-collecting assembly includes a convex mirror, a concave mirror with a central opening and a window, arranged such that light passes through the opening in the concave mirror, is reflected first by the convex mirror and then by the concave mirror, and subsequently passes through the window. The optical assembly is suitable for use in a homing device for guiding a rocket, preventing an optical input component of such a device from being damaged and rendered inoperative from abrasion when exposed to a high-speed air flow containing dense particles. The optical assembly also includes an image-forming function.
