June 2015
Article Synopsis
- This paper explores advancements in the Czerny-Turner optical structure for imaging spectrometers, focusing on correcting astigmatism.
- The traditional components of the system (spherical collimating mirror, plane grating, and spherical focusing mirror) are maintained, but an added cylindrical lens improves performance by fixing astigmatism differences.
- A designed imaging spectrum system operates in the 380-760 nm range, showing impressive resolution and confirming the effectiveness of the proposed optical enhancements for small-scale imaging spectrometers.
[Study and design on Dyson imaging spectrometer in spectral broadband with high resolution].
Guang Pu Xue Yu Guang Pu Fen Xi
April 2014
Article Synopsis
- - The paper presents an improved design of the Dyson imaging spectrometer, featuring a simple and compact optical structure made of a hemispherical lens and a concave grating.
- - It analyzes the broadband anastigmatic imaging condition to minimize optical aberrations and enhance imaging quality, achieving RMS radii of less than 2.5 micrometers.
- - The study also explores modifications to ensure the detector does not contact the hemispherical lens, making the spectrometer more practical for engineering applications, with potential uses in industry and remote sensing.
