摘要
在对航天器敏感材料开展高加速紫外模拟试验的过程中,需要对近紫外辐照模拟的均匀性进行控制,以提高试验模拟的有效性和试验结果的准确性。文章采用氙灯作为紫外辐照源,利用聚光镜、光学积分器和反射/滤光镜,实现了大面积高均匀度的紫外辐照;同时,利用准直镜和发散镜的设计,成功兼顾高加速倍率和较大辐照面积,可实现ϕ300 mm面积上紫外辐照度为15SC、ϕ180 mm面积上紫外辐照度为24SC、均匀性均优于95%的紫外模拟。
In the highly accelerated near ultraviolet(NUV)irradiation simulation tests on the vulnerable materials for spacecraft,it is essential to control the uniformity of the NUV irradiation to improve the effectiveness of the test simulation and the accuracy of the test results.In this paper,the Xenon lamp is used as the NUV irradiation source,while the condenser,the integrator,and the reflector or the filter are used to realize a highly accelerated NUV irradiation with quite good uniformity.At the same time,the collimating mirror and the divergent mirror are designed to realize a high acceleration rate on a suitable large irradiation area.The NUV simulation with an irradiance of 15SC on an area ofϕ300 mm,or an irradiance of 24SC on an area ofϕ180 mm can be realized,with a uniformity better than 95%.
