Brewster Angle Microscopy
Since its first presentation at the LB 6 in
Paris, the Accurion Brewster Angle
Microscope (BAM) has been established as the worldwide standard technique
for the investigation of ultra thin organic films.
BAM1 was the first commercially available instrument. Through continuous
development in close collaboration with several research groups, we have
continued to improve our technology, culminating in the EP³-BAM series.
Cooperation with companies in related fields has also resulted in the
development of a range of interdigitizing products - providing tailor made
solutions for the demands of state-of-the-art research in organic
In addition to their present EP³-BAM, a
high end research tool with a lateral resolution of 1 µm we also offer our MicroBAM
series for film quality control on aqueous sub-phases with a standard

a long lasting experience in Langmuir-Blodgettry. They have been developing and
manufacturing LB instruments for more than 14 years.
Starting in 1991 with the first commercially
available Brewster Angle Microscope BAM1, we have constantly extended
our product palette. In addition to our BAM series, we offer wide range of LB
products: reflection spectroscopy, surface potential sensor, NIMA troughs with
pressure sensor and dipper.
Spectroscopy is a powerful tool in the investigation of the orientation,
association, adsorption, and chemical change of chromophores in monolayers at
the air-water interface.

The EP³-BAM from
is an ideal thin films imaging system. It is a completely "hands-off"
computer-controlled system, using proprietary motor control
displays real-time image of your sample directly on the monitor and features
important image processing functions. An "objective scanner" provides extended
depth-of-field for overall-focused images. The combination of a high power green
laser and excellent objectives allows lateral resolutions of 1 micron, the
current limit of CCD optical detectors.
The powerful software (under windowsXP)
makes operation easy and convenient. As a complete solution, the system comes
including the computer, electronics, and all necessary software needed to begin
measurements on your existing trough, or with one of our integrated NIMA
