Optical Reflectance Measurements for Commonly Used Reflectors

Reflection of light is either specular (mirror-like) or diffuse (retaining the energy, but losing the image) depending on the nature of the interface. In specular reflection the phase of the reflected waves depends on the choice of the origin of coordinates, but the relative phase between s and p (TE and TM) polarizations is fixed by the properties of the media and of the interface between them.

WebFeb 26, 2024 · Precise and accurate measurements of the optical properties of materials are essential for the advancement of optical technology and their applications. Such measurements include reflectance, transmittance, emittance, absorptance, and index of refraction. Many of these quantities depend upon the geometry (incident angles and/or … WebGenerally, the reflectance can substantially depend on the angle of incidence on the sample. Therefore, many optical reflectometers allow one to measure the reflectance for a wide range of incidence angles, but some devices work only with a fixed angle, which of course allows the use of a much simpler optical setup without moving parts.
