摘要 | As linear field imaging by slit led to small aperture and low optical transmittance in imaging spectrometers, a large aperture imaging spectrometer based on prism-grating (PG) component was proposed. The PG imaging spectrometer employed a surface-relief type grating which can reduce the cost and fabrication difficulty of gratings. Although the large aperture imaging spectrometer had higher optical efficiency and time efficiency, the color aberrations and spectral line curvature were difficult to correct. Thereby, the telescope system was unified with the optical splitting system, which enabled the telocentric optical path mach and the aperture match with the perfect correction of spectral line curvature and color aberrations. In addition, an aspheric mirror and correction mirror were mounted to compensate the asymmetry aberration. The results demonstrate that the spectral range of the PG imaging spectrometer is 400-1000 nm, the Modulation Transfer Function(MTF) is greater than 0.65 and the spectral resolution is 2.5 nm. The spectral line curvature is less than 5 m, and color aberrations were less than 8 m in full spectrum. 2017, Science Press. All right reserved. |
