A seeker/receiver system for a moving body, such as for guiding the moving body to a target, includes an optics/receiver portion that tilts as a unit relative to other parts of the moving body. The optics/receiver portion includes a window which may be used to enclose and protect one or both of a pair of receivers or detectors, such as a laser energy detector or receiver, and an infrared energy detector or receiver. By moving the window and the receivers as a unit a set positional relationship is maintained between all of the elements of the optics/receiver portion. This simplifies the optics by obviating the need for all aspects of the window to present the same properties to energy detectors that tilt relative to it. The optics/receiver portion may be tilted using a tilt mechanism such as a gimbal.
