摘要
玻璃表面由于反射作用会使光能损失。为了减少玻璃表面的反射损失,可以通过在表面镀增透膜来解决。研究了多层增透膜对铒硼硅酸盐玻璃可见光透过率的影响。在理论上比较了不同膜系结构(层数不同)的增透膜对铒硼硅酸盐玻璃的增透效果。采用了六层膜的设计,并对镀膜前后玻璃的反射率和透过率进行了测试,玻璃在可见光区的430nm波段到800nm波段的平均反射率从原来的7.5%左右下降到了1%左右,其吸收光谱曲线的最高透过率从未镀膜前的80%左右提高到了97%左右。同时,镀膜后的铒硼硅酸盐玻璃在0.53μm处的透过率仍然保持在0.01%(光密度D0.53=4),而可见光透过率达到了65%,比镀膜前提高了10%左右,玻璃的可视性得到了明显的改善。
The reflection of the surface of glass usually results in the light energy loss. Therefore,antireflective coatings are plated on the surface of glass in order to reduce the loss of surface reflection.The influence of the multi-layer antireflective coatings on the transmittance of visible light of the erbium-borosilicate glass was investigated.At the meantime,the effects of antireflection coatings with different numbers of layers were compared in theory.In addition,the reflectance and transmittance of the erbium-borosilicate glass were tested with a six-layer antireflection coating on its surface.The average reflectance of the light at the wavelength range from 430nm to 800nm descended from 7.5% to 1%,and the maximum transmittance increased from 80% to 97%.The transmittance of the light at the wavelength 0.53μm stayed at 0.01%(the optical density D_(0.53)=4),however,the transmittance of visual light reached 65%,which was enhanced by about 10%,and the visualization of the glass was improved obviously.
