摘要： In a multi-wavelength spectrophotometer using a self-scanning detector, the range of wavelengths to be scanned by the detector is divided into plural subranges. These wavelength subranges are subjected to the wavelength scanning with different integration times respectively. The detector output at the scanning of each wavelength subrange is stored in a memory. Thereafter, the stored data is read out in a form of a continuous wavelength range.

摘要： There is provided a multi-functional spectrophotometer allowing various measurements in which a stigmatic concave grating is employed for selecting the wavelength of the measuring light. A number of miniature type detectors are employed for detecting the diffracted light from the concave grating. Cells containing samples to be measured can be positioned either adjacent to inlet slits at the side of a light source or behind exit slits. These positions of the cells can be easily changed over one with the other. In the former position, absorbances (concentrations) of sample components for a plurality of predetermined light wavelengths can be simultaneously measured. In the later position, not only the absorbance characteristic curve of the sample can be determined, but also the absorbance, fluorescence and turbidity of the sample for a give wavelength can be measured.
