UV-Vis Spectrophotometer with integrating sphere

This spectrophotometer is used for absorption and transmission spectroscopy but the integrating sphere allows diffuse and specular reflectance and diffuse transmittance measurements to be performed. This allows absolute absorption to be calculated as losses due to scattering can be accounted for.
