摘要
近红外吸收滤光片可以用于夜视兼容照明器件。为了研制夜视兼容近红外吸收滤光片,将一种菁染料均匀掺杂在透明塑料聚甲基丙烯酸甲酯(PMMA)中制备了近红外吸收滤光片,研究了菁染料的掺杂量对近红外吸收滤光片夜视兼容能力的影响。结果表明,随着菁染料掺杂量的增加,近红外吸收滤光片的可见光透过率逐渐下降,在近红外区域的吸收能力逐渐增加,光谱辐亮度夜视兼容值逐渐减小且朝着有利于满足夜视兼容要求的方向移动;将菁染料与普通塑料用染料透明黄GS、透明蓝AP-FW配合使用,成功制备出了一种绿色夜视兼容近红外滤光片,该滤光片不仅颜色满足军标中夜视绿A的要求,光谱辐亮度夜视兼容值为9.22×10-12,满足军标中对光谱辐亮度的要求,而且具备优异的光稳定性能。
Near infrared （NIR） absorbing filter can be applied on lighting apparatus for night vision imaging system （NVIS）-compatible lighting. NIR absorbing filters were prepared by doping cyanine dye in polymethyl methacrylate （PMMA） filter to develop the NIR absorbing plastic filter for NVIS-compatible lighting. The influence of cyanine dye＇s dosage on the NVIS compatibility of the filters was studied. The results show that the transmittivity of visible light decreases gradually and the NIR absorbing capacity increases gradually with the adding of cyanine dye＇s dosage, and the NVIS Radiance decreased gradually towards meeting the needs of the NVIS-compatible lighting. A NIR absorbing green filter for NVIS-compatible lighting was achieved by utlizing the cyanine dye and common dyes（Yellow GS and Blue AP-FW） for plastic, the filtegs color was NVIS green A and the filte＇s NVIS Radiance value was 9.22 × 10^-12 , which met the needs of the NVIS-compatible lighting in military standard, and the filter had excellent photostability.
