Simulation and Analysis of Czerny Turner Monochromator for Medical Imaging
Spectral resolution is the important aspect in determining the image quality. This is obtained by adjusting the monochromators like Czerny turners, thereby achieving the required image quality. This turner has advantages like flexible focal length imaging, minimizes the image aberrations, astigmatism etc. This paper focuses on the simulation of Czerny turner using COMSOL Multiphysics modeling software and analysis of its corresponding results for different spectral ranges and numerical aperture values. These results help to understand the optical interfaces and positioning of incident rays on the detector, from which the instrument spectral resolution can be derived.
