Description
The Lambda 950 UV/Vis/NIR is a double beam, double monochromator, all-reflecting optical system which operates in the ultraviolet (UV), visible (vis) and near infra-red (NIR) spectral range. Deuterium and tungsten Halogen light sources. Automatic source change occurs during monochromator slewing; and, programmed optical filters also perform automatic filter change.
