closed while standardizing and taking measurements .

Specular Included/Excluded Port

The UltraScan PRO sphere contains a specular exclusion port door which is closed during specular
included and transmittance measurements and opened during specular excluded measurements. The
position of the door is controlled through the software. See the ULTRASCAN PRO STANDARDIZATION
section for more information on the various measurement modes.
