Solar simulator adopting heat-sink-free collimating mirror

Abstract

The invention relates to a solar simulator adopting a heat-sink-free collimating mirror. The solar simulator comprises a light source system, a main tank of a vacuum system and an auxiliary tank of the vacuum system, wherein a collimating mirror frame is arranged in the auxiliary tank of the vacuum system; a collimating mirror is arranged on the collimating mirror frame; the collimating mirror frame is connected with the inner wall of the auxiliary tank of the vacuum system; the outer wall of the auxiliary tank of the vacuum system is exposed in the air; and the collimating mirror is used for carrying out thermal conduction through the collimating mirror frame and the auxiliary tank of the vacuum system. The solar simulator provided by the invention is simple in structure; the temperature change range of the collimating mirror is small; the service life is long; the surface shape change of the collimating mirror is small; and the stability of the irradiation uniformity of a test surface when the solar simulator works for a long period of time is high.

Description

technical field [0001] The invention relates to the field of photoelectric technology, in particular to a solar simulator using a heat sinkless collimating mirror. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] The environmental radiation received by space targets flying outside the atmosphere mainly includes solar radiation, radiation reflected by the earth's sunlight, and earth radiation. In order to expand the technical approach of space target experimental research, it is necessary to establish a set of technology and experimental equipment that simulates the extreme conditions of the space environment, realistically reproduce the vacuum, low temperature, cold darkness and radiation characteristics of the space environment in the laboratory, and conduct ground simulation verification test.

Problems solved by technology

However, the temperature range from -50°C to 80°C is still large, the collimating mirror is easily damaged, has a short service life, and the surface shape of the collimating mirror will change, which will affect the irradiation of the test surface when the solar simulator works for a long time Uniformity Stability

[0006] Therefore, in the prior art, there is a need for a method that can solve the problem of the short service life of the collimator due to the large temperature range of the collimator when the solar simulator is working, the complex structure of the solar simulator, and the uniformity of the test surface irradiation during long-term work. A solution to the problem of poor stability
