Your Thin Films Visualized
The Accurion EP4 offers a variety of unique features that allow the visualization of your surface in real-time. You will see in real-time the structure of your sample on a microscopic scale. You can measure parameters like thickness, refractive index, and absorption. You can receive maps of selected areas. You can combine the instrument with other technologies like AFM, QCM-D, reflectometry, Raman spectroscopy and many more to receive even more information from your samples. The Accurion EP4 is a modular instrument enabling configuration for your specific measurement tasks. The Accurion EP4, equipped with the standard laser can also be operated as a Brewster angle microscope, typically in LB applications.

04 Air/Water or Liquid/Liquid Interface
The air/water interface is of elementary interest in biophysics as well as in industrial applications. Brewster angle/LIQUID microscopy (BAM) is a powerful technique that allows for real-time visualization of Langmuir-Blodgett monolayers.

05 Bio Interfaces
Biological applications demand high sensitivity observation techniques. Additionally, the environment needs to be controllable in order to avoid influencing or damaging the behavior of observed materials. Imaging Ellipsometry offers highest sensitivity for thickness or surface coverage of mono- as well as sub-monolayers with microscopic resolution.
