An optical system for a multidetector array spectrophotometer includes multiple light sources (10,12) for emitting light of selected wavelength ranges and means for selectively transmitting the selected wavelength ranges of light to respective slits (40,42) of a multi-slit spectrograph for multiple wavelength range detection. The spectrograph has two or more slits (40,42) 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 (46).

摘要:
The present disclosure relates to the field of optical systems, in particular to an atomic emission spectrometer. The envisaged multi-scan optical system (100) is compact and stable. The system comprises an excitation source (104), a hydra fiber cable (106), a wavelength selector (103), a dispersive optical element (101), and a detector (102). The excitation source is configured to emit composite light. The hydra fiber cable has a head and a plurality of tentacles, and is configured to receive the composite light via a second lens. The plurality of tentacles is configured to emit the composite light towards the wavelength selector which includes a plurality of optical slits (s1 - s8) and a plurality of shutters. The wavelength selector is configured to selectively collect and filter the composite light directed by a first lens and the plurality of tentacles by means of the plurality of shutters. The detector is configured to detect the plurality of spectral line scans reflected by the dispersive optical element for spectrometric analysis.
