Definition

An integrating sphere is a hollow spherical cavity with a diffuse-reflecting material inside the sphere that has a spatially uniform surface, and a flat profile of spectral power distribution. The structure of integrating spheres generally consists of a baffle, different apertures, a light source, and a detector. The ideal integrating sphere has the following characteristics:

  1. (i)

    Small detector and external port.

  2. (ii)

    Miniature devices (light source, baffle, and mount) inside the sphere, which cannot affect optical radiation after its first reflection.

  3. (iii)

    The surface of the sphere is a homogeneous Lambertian reflector, with reflectance independent of the wavelength.

In color applications, an integrating sphere is used to produce a uniform light source from a luminaire or for measuring the transmittance or reflectance of a surface in a particular viewing geometry [1, 2].

Overview

As mentioned earlier, one application is for the measurement of the...
