| Abstract: | In optics coating process,spectrophotometer often be used to measure the optics characteristic such as transmittance,relative reflectance,absolute reflectance,and coating's bandwidth,center wavelength of the surface of the optics accessory.The method of the relative reflect of Lambda 900 spectrophotometer is introducesd which is the ways to measure the interface coating relative reflectance of Grin-lens and small optics accessory through add diaphragm accessory as well as improve the measurement calculate method an so on.,The new measurement precision can reach the instrument's requirement. |

| Keywords: | principle of the relative reflect diaphragm melt quartz accessory measurement method |
