Microscopes are an important tool in biomedical research as it allows for detailed observation and imaging of tissues. Since biological materials are opaque by their nature, severe light scattering ...

Infrared microscopy involves the examination of small samples, usually within the 10 to 100 μm range. Spatial resolution becomes a significant concern on the scale. The infrared light's relatively ...

All fibers were analyzed directly without additional modification or sampling accessories. The O-PTIR spectra resemble transmission-like IR spectra in non-contact (far-field) mode. Through spatially ...
