Abstract

The invention relates to a collimating mirror design method for improving the irradiation uniformity, which comprises the following steps of: determining the surface type parameters of the collimatingmirror according to the design requirements of a solar simulator; dividing the collimating mirror into a plurality of unit collimating mirrors, and determining the surface type parameters of each unit collimating mirror; fitting to obtain the spherical curvature radius of each unit collimating mirror corresponding to the corresponding ideal parabolic collimating mirror unit according to the surface type parameters of each unit collimating mirror; designing each unit collimating mirror as a spherical unit collimating mirror based on the spherical curvature radius obtained by fitting; and splicing all the obtained spherical unit collimating mirrors according to the position corresponding relation to obtain a final collimating mirror. According to the collimation mirror design method for improving irradiation uniformity, reducing the deviation of the collimating mirror obtained by final splicing and the ideal parabolic collimating mirror, improving the optical axis direction consistencyof the output light path of the solar simulator, and improving the irradiation uniformity of the system.

Description

technical field [0001] The invention relates to the technical field of collimator mirror design, in particular to a collimator mirror design method for improving irradiation uniformity. Background technique [0002] The solar simulator can simulate the luminous characteristics of the real sun and is used to simulate the solar radiation in the outer space of the earth. It can realistically reproduce the collimation, uniformity and spectral characteristics of the solar radiation in the space environment in the ground laboratory. [0003] Solar simulators generally use an off-axis collimating optical system to obtain higher uniformity of the irradiated body; at the same time, because the symmetric axis of the irradiated body has a certain angle with the optical axis of the light source system, it can eliminate the secondary surface of the irradiated body. The irradiance error caused by secondary and multiple reflections. [0004] The collimating lens of the collimating optical...
