The turbidity ratio method has been extended to the near infrared region. In addition to the usual wavelengths 435.8, 546.1 and 684.3 nm, wavelengths 857.5, 1 074 and 1 346 nm were also used in the measurements. Using a model system of polystyrene latex, it was shown that the turbidity ratio method could be utilized also in this range of wavelengths. Its advantages and shortcomings were demonstrated.
