Abstract

The invention relates to a high-collimation solar simulator optical system with an auto-collimation aiming system, belonging to a solar simulator optical system in the technical field of optics design and aiming at solving the technical problem of providing a high-collimation solar simulator optical system with the auto-collimation aiming system. The high-collimation solar simulator optical system with the auto-collimation aiming system comprises a xenon lamp source, an ellipsoid condenser, a plane mirror, an optics integrator assembly, a first dispersion prism, a second dispersion prism, an emission reticle, an LED light source, an aiming reticle, an ocular lens and a collimator objective. On the basis of the traditional high-collimation solar simulator optical system, an auto-collimation aiming system is added on an optical path of the optical integrator assembly, wherein the auto-collimation optical system comprises a first dispersion prism, a second dispersion prism, an emission reticle, an LED light source, an aiming reticle and an ocular lens. The invention can ensure more accurate zero calibration so as to eliminate the man-made influence and achieve better experimental effect.

Description

technical field [0001] The invention belongs to a solar simulator optical system related to the technical field of optical design. 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. Th...
