1. An apparatus, comprising:

  • a planar base;

    a light source coupled to the planar base and configured to transmit an excitation optical signal through a first surface area of skin to an implanted sensor;

    one or more detectors coupled to the planar base and configured to detect an analyte-dependent optical signal emitted from the implanted sensor through a second surface area of skin in response to the implanted sensor being illuminated by the excitation optical signal, the second surface area of the skin being at least four times the first surface area of the skin;

    a first lens from an array of lenses, the first lens configured to focus at least a portion of the analyte-dependent optical signal onto at least one of the one or more detectors, the first lens defining a first lens axis; and

    a second lens from the array of lenses, the second lens configured to focus at least a portion of the analyte-dependent optical signal onto at least one of the one or more detectors, the second lens defining a second lens axis substantially parallel to and non-coaxial with the first lens axis.
