Operating at f/5, Commander™ UV Raman Spectrometer delivers edge rejection within 5 cm-1 in visible spectral region. Aspheric mirrors correct and optimize imaging performance for excellent signal levels at detector, even with weakly emitting samples. Entrance slit width and intermediate aperture in filter stage allow user to set slope of edge rejection as well as wavelength range. To eliminate water and oxygen absorption, double-monochromator filter stage and sample area may be nitrogen purged.
