Abstract

The invention relates to a design method of an optical integrator, which comprises the steps of determining the position of an expected irradiation uniform plane according to application requirementsof a solar simulator system, wherein the distance between the expected irradiation uniform plane and a collimating mirror is at least 1.5 times of the distance between the collimating mirror and the optical integrator; and configuring the arrangement form of a front lens group and a rear lens group so as to enable optical axis channels of transmitted beams to be in mutual divergence at the collimating mirror, wherein a reference overlapping image plane formed by the collimating mirror is located at the expected irradiation uniform plane. Compared with the existing integrator form in which theoptical axes converge at a point, the method of the invention changes the position of the irradiation uniform plane of the system, thereby being capable of greatly meeting the use requirement of a large distance between the irradiation uniform plane and the collimating mirror.

Description

technical field [0001] The invention relates to the technical field of optical integrators, in particular to a design method of an optical integrator. 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. The solar simulator is mainly composed of a light source, a condenser reflector, an optical integrator, and a collimator. Simulation of the sun at infinity. [0003] As a key component to make the solar simulator produce a uniform irradiated surface, the optical integrator is located between the concentrating mirror and the collimating mirror, which can effectively improve the optical uniformity of the illumination. The optical integrator mainly includes two groups of lenses. The fron...
