1. An apparatus for spatially separating light for use in noninvasively determining an analyte concentration of a subject, comprising:

  • a near-infrared noninvasive analyzer, comprising;

    a near-infrared source;

    a coupling optic configured to couple light from said near-infrared source with an illumination zone on the subject during use;

    a plurality of optically defined detection zones, comprising;

    a first detection zone at a first radial distance from the illumination zone; and

    a second detection zone at a second radial distance from the illumination zone; and

    a set of detectors, comprising;

    a first plurality of detectors optically configured to detect light from said first detection zone; and

    a second plurality of detectors optically configured to detect light from said second detection zone.
