A spectrometer system with structure defining an entrance aperture, dispersing structure, structure defining a plurality of exit apertures, detector structure associated with each exit aperture and a post disperser assembly disposed between an exit aperture and its detector structure.

Spectrometer assembly with post disperser assembly

A positioning mechanism support structure mounted for movement between first and second predetermined positions in a spectroanalytical system includes relative to a reference member by a plurality of stabilizing coupling assemblies, and drive structure for producing motion of the support structure relative to the reference structure between first and second stop structures that define the first and second predetermined positions, respectively. Interlock structure responds to the drive force generated by the drive structure and de-energizes the drive structure in response to the drive force applied to that support structure exceeding a predetermined threshold value.

Spectroanalytical system

A spectroanalytical system with a plurality of radiation sources and structure defining an analysis region that includes means for thermally energizing a sample material to be analyzed. Analysis beam path defining structure includes means for passing a radiation beam from a radiation source along the analysis beam path through the analysis region for modification by sample material in the analysis region. Analysis structure includes radiation dispersing structure arranged to disperse radiation in the analysis beam path with a spectrum and a radiation sensor. First transducer structure moves the dispersing structure relative to the beam path to apply a selected portion of the radiation dispersed by the dispersing structure to the radiation sensor. Source selector structure is disposed in the analysis beam for selecting radiation from one of the radiation sources along the analysis beam path, second transducer structure is coupled to the source selector structure for directing radiation from a particular radiation source along the analysis beam path, and control structure coordinately operates the two transducer structures to apply a particular dispersed wavelength of radiation from the selected radiation source to the radiation sensor.
