    Abstract: A spectrometer assembly (10) comprises a light source (11) with a continuous spectrum, a pre-monochromator (2) for generating a spectrum with a relatively small linear dispersion from which a spectral portion is selectable, the spectral bandwidth of such spectral portion being smaller than or equal to the bandwidth of the free spectral range of such order in the echelle spectrum wherein the centre wavelength of the selected spectral interval is measurable with maximum blaze efficiency, an echelle spectrometer (4) with means for wavelength calibration, an entrance slit (21) at the pre-monochromator (2), an intermediate slit assembly (50) with an intermediate slit (3) and a spatially resolving light detector (5) in the exit plane of the spectrometer for the detection of wavelength spectra. The assembly is characterised in that the width of the intermediate slit (3) is larger than the monochromatic image of the entrance slit generated by the pre-monochromator at the location of the intermediate slit, and means for calibrating the pre-monochromator are provided, which are adapted to calibrate the light of the light source with a continuous spectrum on the detector to a reference position.

    Abstract: A spectrophotometer having functions of both of a double-monochromator and a single-monochromator including a light source, a first spectroscope having a first slit through which light from the light source passes and a first dispersion element for dispersing the light from the first slit, a second spectroscope having a second slit for receiving light dispersed from the first dispersion element for dispersing the light from the second slit, and a third slit for receiving the light dispersed from the second dispersion element. A sample compartment is provided for transmitting the light from the first dispersion element or from the third slit directly to a detector or through a sample to the detector. An optical unit is provided for changing transmitting light paths between a first light path for transmitting the light from the first dispersion element to the sample compartment through a fourth slit and a second light path for transmitting the light from the third slit to the sample compartment. A length of a light path from the first dispersion element to the second slit is equal to a length of a light path from the first dispersion element to the fourth slit.
