1. A detector for detecting thermal radiation in multiple coverage zones, said detector comprising:

  • a support member;

    a first thermal detection sensor supported on and thermally coupled to the support member and arranged to detect thermal energy in a first coverage zone;

    a second thermal detection sensor supported on and thermally coupled to the support member for detecting thermal energy in a second coverage zone; and

    a single optical lens supported on and thermally coupled to the support member and arranged to direct thermal energy from the first coverage zone to the first thermal detection sensor, and to direct thermal energy from the second coverage zone to the second thermal detection sensor, wherein the support member comprises a metallic heat sink maintaining the optical lens and the first and second thermal detection sensors at a substantially common temperature.
