介结了云南天文台太阳光谱仪１９８８年进行的重镀１１块照相透镜增透膜以及镀膜后的使用情况。重镀增透膜前照相透镜的透过率已降低到７７％～８４％，重镀后提高到９２％～９８％。相对于镀膜之前的透过率数值提高１４％～２６％，照相露光时间缩短１倍左右。 Mediated the Yunnan Observatory solar spectrometer in 1988 re-plating eleven photographic lens AR coating and coating the use of the situation. The transmittance of the photographic lens before the AR coating has been reduced to 77% to 84% and to 92% to 98% after the heavy plating. Relative to the transmittance value before coating increased by 14% to 26%, photographic exposure time is shortened by about 1 times.
