The EUV camera optics element of the two phase of lunar exploration will be used the multilayer films reflector,For perfecting and confirming the technics of plating multilayer films reflector,we need plate and measure the multilayer films sample before plating it.The text introduced a small scaled vacuum tester used for measuring the reflectivity of the multilayer films sample. The tester composed of a laser produced plasma sourc,a Mcpherson247 monochromator with a constant deviation angle,vacuum sample room, data collection and disposal system.The working wavelength is from 1 to 120 nm,the stability of spectral radiance is better than ±1%/h,the error of angular resolution is 0.015° .We use the small scaled vacuum tester to measure the reflectivity of the different wavelength of the multilayer films sample. On the fixed angle of incidence,we measure the reflectivity curve of different wavelength. On the basis of the measuring result we can perfect the technics of plating multilayer films reflector.
