  • DARK-FIELD MID-INFRARED PHOTOTHERMAL MICROSCOPY
    Publication number: 20230408805
    Abstract: Microscopic analysis of a sample includes a system using dark-field illumination. A mid-IR optical source generates a mid-infrared beam, which is directed onto the sample to induce a temperature change by absorption of the mid-infrared beam. A visible light source generates a light illuminating the sample on a substrate and creating a scattered field and a reflected field along a collection path of the system. A pupil mask is positioned along the collection path to block the reflected field while allowing the scattered field to pass therethrough. A camera is positioned at an end of the collection path to collect the scattered field and generate a dark-field image of the sample.
    Type: Application
