  • To decrease the influence of external loads and temperature changes on the surface deformation and alignment of a lens, a typical lens support structure was investigated based on the characteristics and technical requirements of carbon dioxide detectors for optical systems and specifications. A radial support structure was proposed and its 3D model was established. In order to verify the reasonability of the structure, the dynamic and static rigidities as well as thermal characteristics were analyzed by using a nonlinear analysis method through CAD engineering analytical software. The analysis results indicate that the first frequency of lens subassembly is 1 301 Hz, and lens surface shape error is as follows:PV/10, RMS/50, Tilt error1. The radial support structure can keep lens centration well and reduce the influence of temperature diversification on the lens surface deformation.These results validate the rationality of structure and satisfy the design requirements.
