Integrated Thermal-Structural Analysis of a Reflecting Optical System with All Metal Components

Abstract:

The thermal deformation of reflecting optical system in the ambient temperature affects the system performance greatly. Based on the results of thermal balance test, the paper has made a full analysis to the deformation of reflecting optical system on the high-low temperature using the finite elemernt method,so as to validate whether the optical system meet the requirement of optical image design and temperature. This method can combine the thermal optical analysis and thermal balance test data effectively ,and therefore the most actual thermal optical anslysis model can be obtained to guide the concept and optimization of reflecting optical system.
