Optical System Lambda 20
The Lambda 20 UV/Vis Spectrometer features an all-reflecting optical system. The
optical components are coated with silica for durability. A holographic grating is
used in the monochromator.
The optical system is depicted schematically in Figure 17.
The monochromator is a holographic concave grating with 1053 lines/mm in
the center.
Two radiation sources, a deuterium lamp and a halogen lamp, cover the working
wavelength range of the spectrometer.
