Grazing incidence reflection spectrometer.

摘要

The present invention consists in grazing incidence reflection spectrometer wherein light (2) is caused to incide on a surface of a sample (1), and an intensity of light (3) reflected from the sample surface is detected, thereby to measure an electronic absorption spectrum of a material adsorbed to the sample surface, characterized in that the incident light (2) is visible light or ultra-violet light, and that the incident light (2) has a predetermined glancing angle (8) to the sample surface.
