The Perkin Elmer Lambda 950 UV-Vis-NIR spectrophotometer displays ultra-high UV/Vis/NIR performance for wavelengths up to 3300 nm, high precision measurements, and for applications such as highly reflective and anti-reflective coatings, color correction coatings. Its wavelength range is 175 – 3300 nm with less than 0.05nm resolution. It is a double beam, double monochromator, ratio recording UV/Vis/NIR spectrophotometer with microcomputer electronics. The detector is a Photomultiplier R6872 for high energy in the whole UV/Vis wavelength range.
