1. An optical detection and orientation system for irradiating a sample material in at least one microchannel wherein said microchannel is in a solid substrate, said system comprising:

  • at least one source of excitation light optically coupled to a movable optical train, said optical train comprising at least one optical element configured to direct said excitation light from said at least one source to said microchannel;

    a carrier, said optical train being supported by said carrier and said carrier being adapted to move said optical train relative to said solid substrate;

    at least one optical element configured to receive light emanating from said microchannel and transfer said emanating light to at least one detector; and

    a data analyzer configured to analyze and control movement of said carrier based on said emanating light.
