The paper presents the analysis of the multimode fibre optic evanescent wave sensor response. Theoretical considerations, based on losses during the single reflection and the complex refractive index, showed non-linearity between the sensor response (absorbance) and the imaginary part of the refractive index, hence, concentration of examined species. To confirm the theoretical predictions, an experiment in the model sensor set-up was performed. As an absorbing species amidoblack dye (naphtol blue black) was used. Good agreement between the experimental results and theoretical predictions was observed.
