Brewster angle reflectometer

A Brewster angle reflectometer is a device used to measure the optical properties of a surface by analyzing how light reflects at a specific angle called the Brewster angle. When polarized light hits a smooth surface at this angle, reflected light has minimal reflection of one polarization, revealing details about the material’s refractive index. This helps scientists and engineers understand surface coatings, film properties, or material composition by precisely measuring the reflected light, facilitating applications in optics, material science, and quality control.
