标准范围
This International Standard specifies measurement procedures for the precise determination of the highreflectance of optical laser components. Up to now, the ISO standardized testing methods for reflectanceof optical laser components have the accuracy limit of approximately 0,01 % (for measurement ofabsolute reflectance) which are not appropriate for measuring the reflectance higher than 99,99 % or,in some cases, measurement accuracy better than 0,01 % is required. The range of application of thisstandardized test method is reflectance 99 % and higher (theoretically up to 100 %).The methods given in this International Standard are intended to be used for the testing andcharacterization of high reflectance of both concave and plane mirrors used in laser systems and laserbasedinstruments. The reflectance of convex mirrors can also be tested by taking into considerationthe radius of curvature of the mirror surface.
