Abstract:
An optical sample X-ray testing apparatus, comprising:an X-ray source configured to radiate X-rays including a group of spectra; a filter provided between the X-ray source and an optical sample and configured to cut off visible light and UV light; at least one line spectrum selecting device provided between the X-ray source and the optical sample and configured to direct substantially one line spectrum among the group of line spectra from the X-ray source toward the optical sample; and an optical characteristics finding device configured to find optical characteristics of the optical sample based on radiation of the substantially one line spectrum through the line spectrum selecting device onto the optical sample, wherein the line spectrum selecting device comprises at least one multi-layered film mirror or at least one X-ray filter, the multi-layered film mirror being configured to reflect the substantially one line spectrum among the group of line spectra, the X-ray filter being configured to transmit the substantially one line spectrum among the group of line spectra.
