英文摘要 | the increased sensitivity of space-based sensors has imposed greater stray light performance goals on telescope design. to meet the demand, a stray light test station for measuring point source transmission (pst) has been built with a lower threshold and higher accuracy. the station is nearly all black with dimensions of 28m long by 8m wide by 9m high. it is coupled with a double cylindrical chamber that reflects the specular light away from the instrument under test. the chamber is a class 6 cleanroom. the station will allow measuring the instruments with up to a 1 meters diameter, and to perform these measurements at visible and infrared wavelengths. the instrument under test will allow to scan at azimuth angles +/-110 degrees, and at elevation +/-15 degrees. the tests were performed to estimate stray light characteristics of two optical instruments. test results demonstrated pst performance below 1x10(-7) at visible wavelengths, and 1x10(-6) at infrared wavelengths. |
