5 Configuration and Operating Principle of the ICPE-9000 

 

5-6

5.5 Spectrometer and Light-Focusing System 

In axial-view observation, light from the ICP is bent 90

°

 by the back-reflect mirror in the cooling jacket, 

it passes through the glass window in the section joining the spectrometer and the cooling jacket, and it is 
reflected by the toroidal mirror and the plane mirror to form an image at the entrance slit. 

In the echelle mounting, the spectrometer mount uses an echelle diffraction grating with 79 grooves/mm 

and a blaze angle of 63.4

°

. 

Light that passes through the pinhole (rectangular) entrance slit is converted to parallel light by the 

collimator mirror (parabolic mirror), and is divided (in a vertical direction) according to wavelength by 
the echelle diffraction grating. Then the light is divided (in a horizontal direction) according to order by 
the prism, it is reflected off the Schmidt mirror in order to correction aberrations, and it is reflected off 
the telemeter mirror (concave mirror) to form an image at the CCD detector.
