JASCO | Grazing Angle Reflectance
Why used Grazing Angle Reflection Accessories?
→ Reflection Absorption Spectroscopy has the benefit of greater sensitivity – up to 1 or 2 orders of magnitude compared with transmission.
When parallel polarized light is incident to a metal surface, the electric vectors in the incident and reflected light interfere to mutually strengthen and form a vertical standing wave.
The interaction of this stationary wave with a thin film on the metal surface, causes an absorption that is stronger than simple transmission measurement.
