宽谱光源平均波长测试系统光路设计仿真

Based on the pixel resolution formula and the Gaussian beam transmission theory, an optical structure of test system based on linear array InGaAs photodetector was designed to test the average wavelength of broad spectrum light source. The optical structure model was established in the Zemax optical software, and the optical structure parameters of the test system were optimized. According to the established ptical model, the influence of position deviation on the beam collimation and the system energy efficiency was analyzed. Corresponding curve was obtained, providing a guidance for the design and assembly of the average wavelength test system of broad spectrum light source.
