Abstract

PURPOSE:To accurately measure the contamination of rinsing water on the basis of optical absorption by making an ultraviolet optical ray having a wavelength shorter than 230nm pass through the rinsing water. CONSTITUTION:The optical ray from a measuring light source 2 is introduced through a reflecting mirror 3 and slits 4 and 51 into a casing 5. Moreover, only the ultraviolet ray, which enters a diffraction grating 53 through a reflecting mirror 52 which has a wavelength of 195nm, is introduced into a reflecting mirror 54. The ray reflected from the mirror 54 is introduced through a reflecting mirror 55 into the slit 56 of the casing 5 and is reflected by a reflecting mirror 6 so that it is guided into a half-mirror 7. This mirror 7 devides the ultraviolet ray so that the resultant spectra are introduced through reflecting mirrors 8 and 9 into the slits 101 and 102 of the casing 10. The rays from the slits 101 and 102 are guided through a reference cell 103, which is filled up with pure water containning no contaminant, and a flow cell 104, through which the rinsing water has been made to flow, so that they are fed through the slits 105 and 106 and through the reflecting mirrors 11 and 12 to the electrodes 131 and 132 of a photocell 13. The electric signals coming from the electrode 133 through the cells 103 and 104 and having values proportional to the intensity of the ultraviolet ray are compared so that the contamination of the water is determined from the optical adsorption relative to that of pure water.
