WebFig. 4-2 shows an integrating sphere attachment used to measure relative diffuse reflectance. When using an integrating sphere, a material such as barium sulfate or specialized fluorine-based polymer (see Note 1) is used as the reference plate (sometimes referred to as a white reference plate). Web8 jul. 2014 · The whole point of the integrating sphere is to INTEGRATE the light over a KNOWN unit area that is meant to be 100% uniform, the sphere is designed to reflect a beam/source of light over and over again to create uniformity. Integrating spheres are not just used to measure light, they can also be used to create a uniform beam.
Web28 apr. 2024 · An integrating sphere may be thought of as a diffuser which preserves power but destroys spatial information. It is typically used with some light source and a detector for optical power measurement. A similar device is the focusing or Coblentz sphere, which differs in that it has a mirror-like (specular) inner surface rather than a … Web22 dec. 2011 · Integrating Sphere Setup for the Traceable Measurement of Absolute Photoluminescence Quantum Yields in the Near Infrared Christian Würth , Jutta Pauli , Cornelia Lochmann , Monika Spieles , and Ute Resch-Genger * View Author Information Cite this: Anal.
