An improved detector assembly having decreased sensitivity both to Narcissism and to stray light ghosting is disclosed herein. The improved detector assembly of the present invention includes a housing having an input aperture in communication with a chamber within said housing. A detector for sensing electromagnetic energy passing through the input aperture within a first field of view is mounted within the chamber. Also mounted within the chamber is a detector mirror for reflecting energy passing through the input aperture within a second field of view outside of the first field of view. The improved assembly of the present invention further includes a second mirror mounted within the chamber for reflecting energy reflected by the first mirror through the input aperture
