1. An apparatus for detecting light transmitted from a composition, the apparatus comprising:

  • a stage for supporting a composition in an examination site, the composition being contained in a spatial volume lying between boundary interfaces located at different points along a Z-axis, wherein the Z-axis is substantially perpendicular to tie stage;

    an automated registration device that automatically brings successive compositions and the examination site into register for successive analysis of the compositions;

    a light source positioned to deliver light to the composition in the examination site;

    a detector positioned to receive light transmitted from the composition in the examination site;

    an optical relay structure located between the light source and the detector, the optical relay structure being capable of transmitting light substantially exclusively from a sensed volume of the composition, wherein the sensed volume is spaced substantially away from at least one of the boundary interfaces of the composition; and

    a Z-axis optical adjustment device that automatically adjusts positions of the sensed volume along the Z-axis between and spaced away from the boundary interfaces.
