Reflection spectroscopy is a powerfull tool for the investigation of orientation, association, adsorption and chemical change of chromophores in monlayers at the air water interface. The variable angle RefSpec2 VA features precision motorized angle-of-incidence adjustments and a motorized polarizer and analyzer.
For this reason it allows the investigation of orientation effects and optical dichroism in thin films. The instrument is designed to work for Langmuir and LB films, using precise calibration methods. A cooled back-thinned CCD detector provides the required sensitivity. It is equipped with a Xe-light source for an operation in the range of 240 - 980 nm.
Typical samples:
- Dye monolayers
- Proteins
- LB-films
- Tensides
- Fatty acids
- Liposomes interacting with lipid films
- Proteins interacting with charged/uncharged lipids
