This method is easier to interpret than the objective stop method used by the older ML Series due to the presence of two complementary colors in the same image, so that the wavelength of the refractive index match can be more closely determined. Below are photos of results using the different methods. Further details are available in the following guide: Asbestos: The analysts’ guide for sampling, analysis and clearance procedures References
