The Perkin Elmer Lamda 900 UV/VIS/NIR spectrometer is a double-beam, double monochromator ratio recording system with pre-aligned tungsten-halogen and deuterium lamps as sources. The wavelength is from 175 to 3300nm with an accuracy of 0.08 nm in the uv-visable region and 0.3nm in the nir region guaranteed. It has a photometric range of +/-6 in absorbance mode.
Accessories available include a 60 mm Spectralon coated integrating sphere with a range from 200 to 2500 nm for measurement of samples of high optical density. A common-beam depolariser for measurements with depolarised light in the 190 to 2600 nm range is also available.
