1. An optical detection system for generating and detecting a beam of electromagnetic radiation having an intensity, comprising:

  • a source for producing the beam of electromagnetic radiation;

    a body, that is at least partially transparent and comprises an ATR-sensor layer on at least a portion of the body, having an entrance surface for the beam of electromagnetic radiation, an internally reflective surface that reflects the beam transmitted through the entrance surface, and an exit surface through which the beam reflected from the second surface exits the transparent body;

    a distribution device between the beam source and the body;

    wherein the distribution device redistributes the intensity of the beam from a nonuniform intensity distribution to a substantially uniform intensity distribution;

    a detector that detects the beam of electromagnetic radiation exiting the body.
