Integrating Spheres light measurement KONICA MINOLTA SENSING AMERICAS

Two Global Leaders. One Complete Solution. Konica Minolta Sensing Americas provides advanced optical technology that precisely measures the elements of color and light. Their products have become a staple in research and manufacturing environments, helping organizations to meet product quality and operational goals with less waste, time, and effort. This commitment to creating value for customers is the core principle behind the Konica Minolta brand, and has led them to develop the world’s first portable spectrophotometer and the first light meter used on board a spacecraft (Apollo 8). It’s also...

The Integrating Sphere The Working Principle Aspects of Measurement Reality Using integrating spheres to determine the radiant power or luminous flux from light sources is one of the most important procedures in light measurement. The interior surface of the hollow sphere is coated with a diffuse reflecting material, e.g. barium sulfate (BaSO4), and the integrating sphere therefore guarantees complete mixing of the radiation. Multiple reflections ensure that the light is distributed uniformly throughout the sphere, independently of the original spatial radiation pattern of the light source. A...

Self-Absorption Correction The test object itself contributes to the absorption of light radiation in the integrating sphere. This form of interference known as self- absorption can result in a significant attenuation of light radiation and leads to deviations in measurement. This attenuation becomes more pronounced as the test specimen becomes bigger and Various Self-Absorption Spectra darker. A self-absorption correction with the assistance of a suitable auxiliary light source is therefore essential for precise measurements. A halogen lamp covering a wide spectral range is typically used for...

Integrating Spheres for All Applications Instrument Systems developed a complete family of integrating spheres in the ISP Series with the objective of marketing a broad spectrum of sizes and functionalities. Integrating spheres with diameters from 75mm to 2m therefore allow the characterization of a wide range of different light sources with a very high level of precision. A key issue in selecting a suitable sphere for the designated application is the maximum size of the sample to be measured. The size of the integrating sphere should increase with the size of the light source in order to keep...
