Title: Permeability measuring sample, manufacture thereof, and permeability measuring method
Inventor: JINBO HIROKI
IPC: G01N1/36
Filed: 1995-03-28
Abstract: PURPOSE: To prevent a measurement error in measuring the permeability of a raw material by removing the surface roughness, residual impurities such as an abrasive material, and a structural defect caused by the residual stress generated by machining, and setting the surface loss of the measuring wavelength of the polished face of a sample to a specific value or below. CONSTITUTION: Specifications of a permeability measuring sample are set to the parallelism of 30sec or below, the face accuracy of about the same as that of the parallelism, the surface roughness rms=10Å or below, the internal absorption coefficient of 0.1%/cm for stable measurement. The surface loss occurs when various components contained in an abrasive such as the main components CeO2 , Al2 O3 and diamond abrasive grains of the abrasive of an optical raw material remain as the impurities remaining on the surface of the sample. The effect of the metal impurities can be removed when high-purity SiO2 fine grains are used for finish polishing. The structural defect caused by the residual stress can be removed by the acid and alkali cleaning method. The ultraviolet cleaning of the sample before measurement is effective.  The surface loss of the measuring wavelength is set to 0.1% or below.
