Observing and Measuring Contaminants

Introduction

In contaminant analysis, it is important to check for significant differences between the contaminant and normal areas by measuring the contaminant together with an area that is assumed to be normal in the vicinity of the contaminant. If the border between the contaminant and normal area is unclear, the measurement area of the contaminant can be determined by extending the observation area of which is assumed to be normal and sequentially comparing measurements. The AIM-9000 infrared microscope is equipped with a wide- field camera (option) capable of observing a maximum field of view (FOV) of 10 × 13 mm. This enables efficient observation and checking over an extended range of a measurement area that includes contaminants. In this article, we introduce an example of using the wide-field camera in contaminant analysis.
