Brewster Angle Microscopy is a powerful label-free imaging technique for investigating ultra-thin organic films on various surfaces. In particular monolayers at the air-water interface and Langmuir-Blodgett films on solid substrates.

Brewster Angle Microscopy for investigation of organic ultra-thin films

Overall-focused images in real-time

Monolayer of DMPE during first-order phase transition, contrast in domains caused by long range orientation order.

The new nanofilm_ultrabam provides overall-focused images in real-time! Brewster-Angle-Microscopes observe the sample under an angle and thus only one focused line is displayed.

Until now, a so-called focus scanner has to be used to receive an overall focused image. The new generation of Brewster-Angle-Microscopes overcomes this problem. Due to an advanced optical setup the image displayed by the nanofilm_ultrabam is in focus through the entire field of view without use of a focus scanner. This is extremely advantageous for all floating monolayers and enables a researcher to observe his samples even in real-time!

The lateral resolution of the instrument is 2µm with a field of view of approx. 720 x 400µm. It is designed for the air/water interface but will also work on popular glass substrates due to a variable angle-of-incidence ranging from 52° to 57°.

As a restriction, the nanofilm_ultrabam is designed as a pure Brewster-Angle-Microscope which cannot be upgraded to an Ellipsometer.
