Integrating sphere is used to measure the diffuse reflectance of solid sample and powder, as well as measure the transmittance of the glass and membrane. Integrating sphere can analyze the chrominance, color difference, and whiteness.

Optics principle

The light emitted by the sample accesses to the integrating sphere at angle 0°, and the reference accesses to the integrating sphere at angle 8°. Then, we can measure the diffuse reflectance of the sample at 0°and diffuse reflectance and transmittance of the reference at 8°.
