Optical system of solar simulator

Abstract

The invention relates to an optical system of a solar simulator. An optical integrator component of the optical system consists of two element lens arrays, each element lens array is formed by a plurality of hexagonal element lens hermetically connected and arrayed and optically contacting on an optical contact plate, the two element lens arrays are reversely mounted on the same optical axis, the front element lens array is a field lens array and the rear element lens array is a projection lens array. A xenon lamp is arranged at the first focus of an elliptical light condensing lens, the field lenses in the optical integrator component are arranged at the second focus of the elliptical light condensing lens, the projection lenses in the optical integrator component are arranged between the field lenses and al light-beam collimation angle diaphragm which is arranged on the front focal plane of a collimation objective lens, light emitted by an xenon arc of the xenon lamp is reflected by the elliptical light condensing lens and a planar reflecting lens, condensed and projected onto the field lenses and converted into parallel light after passing the field lenses and the projection lens, and parallel light emitted by the projection lenses can be condensed and projected onto an irradiation surface through the collimation objective lens. The requirement that solar light beam collimation angle and output energy density can be solar constants can be met.

Description

technical field [0001] The invention belongs to the technical field of optical design and relates to a solar simulator optical system. Background technique [0002] A solar simulator is a test or calibration device that simulates the characteristics of solar radiation under different air quality conditions indoors. The development of solar simulation technology is closely related to the development of space science in my country. Solar simulators have become an important part of space environment simulation experiments on the ground in my country's space science. Solar simulators are mostly used for ground environment simulation tests of space vehicles, and are the main components of space environment simulation equipment, providing spacecraft with uniform, collimated and stable light irradiation that matches the solar spectral distribution. In the spacecraft vacuum thermal environment test, the solar simulator is the most realistic and accurate heat flow simulation method...

AI Technical Summary

Problems solved by technology

[0004] Usually, the optical system of the solar simulator used in the laboratory to simulate the characteristics of solar radiation in space cannot satisfy the collimation angle of sunlight and the output energy density in the simulated solar radiation characteristics at the same time due to the mutual constraints of the design parameters of the optical system. These two indicators are greater than a solar constant
