Spectrometer for generating a two dimensional spectrum
摘要
The present disclosure concerns a spectrometer (10) and method for generating a two dimensional spectrum (S). The spectrometer (10) comprises a main grating (3) and cross dispersion element (2). An imaging mirror (4) is arranged for reflecting and focussing dispersed radiation (R3) from the main grating (3) towards an image plane (IP) for imaging the two dimensional spectrum (S) onto an image plane (IP) of the spectrometer (10). A correction lens (6) is arranged for correcting optical aberrations in the imaging of the two dimensional spectrum (S) in the image plane (IP). The imaging mirror (4) and correction lens (6) have a coinciding axis of cylindrical symmetry (AS).
