摘　　要：讨论了在垂直照射/垂直接收几何条件下,石英玻璃管光谱透射比测试中曲面的影响及解决措施。检测透射比时应在光路中加入适宜的光阑或调整狭缝宽度来控制光斑宽度,使用样品支架固定样品,让大部分光接近垂直入射,减少曲面测试位置边部的影响,按照曲面样品的测试要求进行测试,从而保证石英玻璃管光谱透射比检测结果的准确性。This paper discusses the influence of curved surfaces on the spectral transmittance test of quartz glass tubes under vertical irradiation/vertical reception geometry conditions,and proposes solutions.When detecting the transmittance,an appropriate diaphragm should be added to the optical path or the slit width should be adjusted to control the spot width.The sample holder should be used to fix the sample,allowing most of the light to approach vertical incidence and reducing the influence of the edge of curved surface test position.The testing should be carried out according to the test requirements of the curved surface sample to ensure the accuracy of the quartz glass tube spectral transmittance detection results.
