摘要
将两种近红外吸收剂添加到丙烯酸树脂基体中再与PET薄膜复合,制备了可用于夜视兼容照明的双层复合型近红外吸收滤光片。研究了两种近红外吸收剂的吸收特性,以及近红外吸收剂添加量与滤光片吸收性能的关系,并确定了两种近红外吸收剂的用量。所制备的滤光片在660～930 nm波长范围内的光线平均透过率为0.10%,能有效吸收发光器件的干扰光,是一种性能良好的近红外吸收滤光片。另外,经过测试表明滤光片强度大、热稳定性较好,具有良好的应用性能。
Near infrared（NIR）absorption filters are prepared by NIR-dyes and optical plastics.These NIR absorption filters can be applied to light apparatus for night vision imaging system（NVIS）which is compatible with lighting.The optical performance of the filters is studied under different dye dosage.The results show the optical properties of the filters can be easily controlled by changing the amount of NIR-dyes.Besides,there is a good linear relationship between absorbance and NIR-dyes dosage.A NIR absorption filter with optimal dye dosage has been prepared.The filter shows strong absorbing ability in the region between 660nm and 930nm.Meanwhile,the filter has sufficient transmittance between 400 nm and 630 nm.The test result shows that the filter has good application performance.
