The Perkin-Elmer Lambda 950 is a high performance UV/Vis/NIR spectrophotometer capable of making measurements in the 190-3300 nm range. The extreme versatility of this instrument permits the acquisition of spectra from almost any type of sample. The current suite of sampling accessories permits acquisition of transmission (variable angle), diffuse transmission, specular reflectance (variable angle: absolute and relative), diffuse reflectance, and total reflectance spectra. A small spot focusing accessory permits analysis of samples as small as 2 mm x 2 mm without a significant decrease in S/N.
