A high performance UV-Vis-NIR spectrophotometer. Using two light sources (Deuterium UV lamp and QI Vis lamp) on the excitation side and a photomultiplier tube and a PbS NIR detector on the detection side, it can measure the optical transmittance of thin-films and liquids in the extended photometric range 175 – 3300 nm.
