The solar simulator can simulate the collimation, uniformity and spectrum of the sunlight accurately, which provides higher precision space thermal external flux in the vacuum thermal tests of spacecraft. These solar simulators usually are installed on the vacuum chambers. Its light source is outside the vacuum chamber, the light incidents into the chamber by the optical vacuum sealed window. In order to get uniformity irradiation testing volume, the off-axis collimating solar simulator is selected which installed on the KM6 large vacuum chamber. The main chamber is vertical to place the test-articles, which has the overall height of 22000mm, the diameter of 16000mm. The auxiliary chamber is horizontally to place the collimating reflector of the solar simulator, which has the overall height of 13000mm, the diameter of 7500mm. Thesolar simulator is included optical system, cooling system and control system. The optical system consists of the collector mirrors, the collimating reflector and the optical integrator. This solar simulator is developed successful, and it has finished a vacuum thermal test of the camera. In the test the irradiance of the solar simulator is 1420W/m2, it worked more than 100 hours. The test is successful, and gets more valuable experimental data.","PeriodicalId":298149,"journal":{"name":"Optical Metrology and Inspection for Industrial Applications VIII","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127501356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to study the properties of materials and the application of multi-wavelength laser interferometer, a new method of measuring refractive index and dispersion of materials is proposed. The multi-wavelength laser interferometer is designed and built based on the principle of the Fizeau interferometer. It integrates five kinds of laser bands with a wide coverage range through a splitting prism, and can quickly change the measurement wavelength during remeasurement and improve the detection efficiency. In order to further verify the refractive index measurement method, a parallel plate is taken as an example to measure the refractive index. The multi-wavelength laser interferometer combined with variable wavelength standard spherical mirror is used to measure the displacement of ray focus in the case of parallel plate or not, and the refractive index of parallel plate is calculated by geometric optics. The refractive index corresponding to each wavelength is measured, and the refractive index curve of the parallel plate material is calculated by Conrady formula and ACF formula by fitting polynomial method using the measured data, and then the dispersion coefficient of the material can be calculated. The comparison results show that the ACF formula can be used to calculate the refractive index of materials accurately in a larger band range. The experimental results also show that the multi-wavelength laser interferometer has the advantage of measuring multi-wavelength transmission wavefront and can also play a role in more measurement applications.","PeriodicalId":298149,"journal":{"name":"Optical Metrology and Inspection for Industrial Applications VIII","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127604352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
