WebbLaser diffraction measures particle size distributions by measuring the angular variation in intensity of light scattered as a laser beam passes through a dispersed particulate sample. Large particles scatter light at small angles relative to the laser beam and small particles scatter light at large angles. The angular scattering intensity data ... WebbSmall Angle X-ray Scattering (SAXS) is an analytical technique giving access to information about the structure of materials at the nano- and meso-scale. Measurements can be made on almost any sample, but most often is used for soft matter and nanostructured materials.

In geometric optics, the paraxial approximation is a small-angle approximation used in Gaussian optics and ray tracing of light through an optical system (such as a lens). A paraxial ray is a ray which makes a small angle (θ) to the optical axis of the system, and lies close to the axis throughout the system. Generally, this allow… WebbSmall- and Wide-Angle X-Ray Scattering (SAXS/WAXS) with Temperature-Controlled Stages Makes Phase Identification Faster than Ever. Microscopy Today 2024, 29 (6) , 30-36.
