摘要： An optical system for a multidetector array spectrophotometer which includes multiple light sources for emitting light of selected wavelength ranges and means for selectively transmitting the selected wavelength ranges of light to respective slits of a multi-slit spectrogrpah for multiple wavelength range detection. The spectrograph has two or more slits which direct the selected wavelength ranges of the light spectra to fall upon a dispersive and focusing system which collects light from each slit, disperses the light by wavelength and refocuses the light at the positions of a single set of detectors.

摘要： Incident slits and exit slits are provided separately on corresponding optical axes incident simultaneously on a spectroscope from a sample atomizing unit. A mechanism for changing the widths of the respective incident slits and exiting slits is provided such that the slit widths optimal to the respective elements to be measured are set on the corresponding optical axes to thereby realize high sensitivity analysis of all the elements to be measured simultaneously.
