Specifies measurement procedures for the precise determination of the specular reflectance and regular transmittance of optical laser components.

This International Standard specifies measurement procedures for the precise determination of the specular reflectance and regular transmittance of optical laser components. The accuracy of the described test methods exceeds that of measurement procedures outlined in ISO15368 by several orders of magnitude.
