摘　　要：为了研究入射角度对含钴阳极氧化铝膜近红外偏振光谱特性的影响,采用阳极氧化的方法制备了阳极氧化铝膜,向其孔中镀入了钴,然后利用UV-3101PC型分光光度计对其进行了透射光谱测试,并在入射角分别为30°和45°时测试了其偏振光谱。结果表明,这种含钴阳极氧化铝膜在近红外波段具有良好的透射率和消光比,且消光比随着入射角的增大而显著提高。In order to study effect of incident angles on IR polarizing property of Co-A12 03 film, Co was implanted into the pores of anodic alumina by means of electroplating. Its transmittance spectrum was measured with UV-3101PC spectral photometer, and its polarizing spectrum was tested at the incident angles of 30° and 45°respectively. The experimental result indicates that such anodic alumina film with Co columns has good transmittance and extinction ratio in the near-infrared waveband, and the extinction ratio improves notably with increase of the incident angle.
