Abstract:
1. A spectrophotometric system comprising: (a) an integrating sphere that includes a sample port, an SCE measurement port and an SCI measurement port; (b) a first plurality of mirrors positioned relative to said integrating sphere for reflecting and directing an SCE beam emitted from said integrating sphere toward an SCE fiber block; (c) a second plurality of mirrors positioned relative to said integrating sphere for reflecting and directing an SCI beam emitted from said integrating sphere toward an SCI fiber block; and (d) first and second focusing lenses positioned intermediate said first and second plurality of mirrors, respectively, for focusing said SCI and SCE beams, said first and second focusing lenses being mounted to a lens carrier that is movably mounted relative to said integrating sphere; and (e) a drive mechanism that is coupled to said lens carrier and operative to reposition said lens carrier relative to said integrating sphere.
