A UV-Vis-NIR spectrophotometer Perkin-Elmer Lambda 950 is available in the DCMI. This spectrophotometer can operate “classically”, in transmittance mode, typically for solutions. In addition, it is possible to use an integrating sphere (150 mm diameter) for diffusive samples (either in transmittance or in reflectance), or a “Universal Reflectance Accessory” (URA) for variable angle specular reflexion for films of thin layers (between 8 and 70°).
Energy range :
190-3300 nm in transmittance and specular reflexion
190-2500 nm in the integrating sphere
