1. A sample plate scanning system, comprising:

  • a head assembly with a first arm portion, a second arm portion, and a connecting portion rigidly coupling said first and second arm portions;

    a first transport system coupled to said head assembly for scanning said head assembly along a first axis;

    a second transport system coupled to said head assembly for scanning said head assembly along a second axis, said second axis substantially orthogonal to said first axis;

    a sample plate holder for holding a sample plate in a sample reading position, wherein said sample plate is interposed between said first arm portion and said second arm portion when said sample plate is in said sample reading position;

    a source of radiation coupled to said first arm portion, wherein said radiation is directed along a first optical path from said first arm portion towards said second arm portion; and

    a detector coupled to said second arm portion, wherein said detector detects radiation along said first optical path, said detector outputting a signal corresponding to an amplitude associated with said detected radiation.
