Design Simulation of Czerny–Turner Configuration-Based Raman Spectrometer Using Physical Optics Propagation Algorithm

We report the design simulation of Raman spectrometer using Zemax optical system software. The is based on Czerny–Turner configuration, which includes an consisting entrance slit, two concave mirrors, reflecting type diffraction grating and image detector. system’s modeling approach suggested by introducing corresponding relationship between detector pixels wavelength, linear CCD receiving surface length dimension. simulations were carried out POP (physical optics propagation) algorithm. Spot diagram, relative illumination, irradiance plot, modulation transfer function (MTF), geometric encircled energy simulated for designing spectrometer. results a 527 nm wavelength laser as excitation light source are presented. present was designed in sequential mode spectrum observed from 530 to 630 nm. analysis shows that efficiency quite good, predicting it could build efficient cost-effective diagnostics.
