-**Note**: The integrating Sphere is made from Spectralon™. While this material provides excellent spectral reflectivity and spectral flatness it is also very sensitive to contamination and due to the porous nature of its surface collects impurities easily. Any impurities will change the reflectiveness of the integrating sphere and thus might influence the measurements. +**Note**: The integrating Sphere is made from Spectralon™.

-Therefore, handle the integrating sphere carefully avoiding any exposure to dust or other impurities. Avoid spilling sample into the sphere or the sample holder.+Therefore, handle the integrating sphere carefully avoiding any exposure to dust or other impurities.
