An integrating sphere is frequently used to examine luminaire or light source brightness, chromaticity coordinates, CCT, dominant wavelength, peak wavelength, etc. The traditional integrating sphere is the IS-*M, which LISUN has already stopped manufacturing in favor of the IS-*MA, which uses a molding method. It is your finest choice to take into consideration if your application calls for the measurement of a beam that is widely divergent.

Lumen is a unit of measurement for the total amount of visible light emitted by a light source. It is an important parameter in lighting design and evaluation, as it reflects the brightness and effectiveness of a lighting system. To accurately measure lumen output, a spectroradiometer system with an integrating sphere is commonly used. In this technical article, we will discuss how to test lumen by integrating sphere spectroradiometer system.
