    • Abstract
  • The temperature change can affect the change of the shape and interval of the surfaces of the ultraviolet(UV) lens. In order to study the effect of the temperature on the imaging quality of the UV lens, the method of thermal/structural/optical(TSO) integrated analysis was used. The basic processes and key technologies of the TSO integrated analysis were discussed and the Zernike polynomials was used as the interface between structural analysis and optical analysis. Based on the design of the optical system and mechanical structure of the UV lens, the thermal-structural model of the lens was established and the changes of the surface shape and lens spacing were obtained. Finally, the results were coupled in the optical design software, then the image quality was further analyzed. The analysis results show that, in the working range of the lens, the design value of the modulation transfer function (MTF) at 12lp/mm is about 0.7, which can meet the use requirements of hyperspectral imaging spectrometer. At the same time, it also provides a reference for the analysis of the final machine of the spectrometer.
