Spectroscopic nanoscopy (SN) plays a key role in chemistry and cell biology, due to its advanced capabilities in capturing the spatial and spectral information of single molecules. This technique utilizes an imaging spectrometer (IS) equipped with a grating for SN imaging. The grating-based IS has been widely used due to the system’s simplicity. However, optical aberrations are inherent to the grating- based IS and potentially compromise image quality, which necessitates a thorough investigation of the aberrations and their influence on SN imaging. To the best of our knowledge, there has been a lack of rigorous investigation of aberrations of the grating-based IS. In this work we theoretically evaluate the grating-based IS using a ray-tracing model, and examine the aberration effects on calibrating spectral images. This study reveals that the spectral beam exhibits various types of aberrations, including coma, astigmatism, and defocus. Moreover, we confirm that these aberrations introduce differences in spectral- dispersion and spectral-calibration errors in spectral images. We believe that these comprehensive anal- yses underscore the importance of mitigating aberrations in a grating-based IS, aiming to enhance both the spectral precision and reliability of the SN system.
