積分球基本上是一種量測工具，是光的收集者。由外面打入積分球的光經過收集，在球殼內部形成擴散效果，達到均勻光的效應。再經過套在積分球球殼上的光偵測器可經確作光，流明、色度的量測。積分球內部包含一個遮板，保護偵測器不要直接照射到進來的光，造成量測誤差。積分球內部塗佈高反射率的材料-硫酸鋇，可達到98%的擴散效果。光譜範圍是包含紫外線、可見光、不可見光全波段 200-1800nm。
Integrating Spheres generally function as a light collector.  The collected light can be used as a diffuse illumination source or as a measurement source.  The basic principle of operation is that light enters the integrating sphere through the sample port, goes through multiple reflections and is scattered uniformly around the interior of the sphere.  A photo detector which is placed at the port in the sphere wall sees an output which is completely independent of the angular properties of the input light. A baffle placed inside the sphere, is used to prevent the detector from directly viewing the "hot" spot where the input beam of the source initially strikes the sphere wall. The inside of the integrating spheres are made out of highly reflective diffuse material; that gives a light diffuse reflection(>98%) over a wide wavelength range(200-1800nm), covering UV, VIS, and NIR spectral regions.
