Macro evaluation is traditionally a subjective test. However through the use of state of the art software, the impact of the human element is significantly reduced which allows for more comparative (objective) results which are repeatable and quantifiable.
This is a evaluation method based on visual analysis through the use of a Stereoscope / Macroscope. This allows the evaluator to examine the prepared surface which has been polished and etched and then compare what they see to an international testing code. Sample preparation is key to a successful evaluation. Hence MTL has aquired fully customized and automated grinding and polishing equipment.
