| titleOfInvention | Optical path structure and spectrometer of immersion echelle spectrometer |
| abstract | The invention relates to the technical field of imaging spectrometers, and in particular provides an optical path structure of an immersed echelle grating spectrometer and a spectrometer. The optical path structure includes an incident slit, a collimation system, a primary dispersion system, a secondary dispersion system, a focusing system and a detection system. The detected substance enters the incident slit, and the generated incident beam is incident on the collimation system, and after being collimated by the collimation system, it becomes a parallel beam; the parallel beam passes through the primary dispersion system. The first dispersion is carried out by the secondary dispersion system for the second dispersion to obtain a two-dimensional spectrum; the two-dimensional spectrum is imaged to the detector after being focused by the focusing system. The optical path structure and spectrometer provided by the invention not only greatly improve the efficiency and spectral resolution of the optical system, but also make the spectrometer more compact in space, and at the same time, for the refrigeration type infrared spectrometer, the stability of the system is improved. |
