Visualisation of monolayer films can now easily be performed using the new Nima MicroBAM that employs the technique of Brewster Angle Microscopy to detect changes in the refractive index of the water surface in the presence of surfactant molecules. This is useful for determining the homogeneity of compressed monolayer films, domain sizes, shapes and packing behaviour. Although it can be used as a stand-alone device above any air-water interface, when used in conjunction with a Langmuir Trough it can examine film domain structure evolution with time and at various surface pressures. The rigidity of a monolayer material can also be determined from imaging of compressed films during expansion to larger confinement areas.

Transparent materials can be imaged with high contrast at an effective magnification of 40x. The sampling area is 4.0 x 3.6mm, displayed as a greyscale image of 640 x 480 pixels.

The MicroBAM provides real time imaging of monolayers for capture as video footage or image sequences, ideal for both animated scientific presentations and written publications.

The compact, elegant design ensures the equipment will fit neatly into your existing laboratory setup. The portable instrument can easily be used around a laboratory with several Langmuir troughs.

The Nima MicroBAM comes complete with a computer interface unit, power supply, cables, user manual and control and image capture software.

Details of the principle of operation of this instrument can be found in the Monolayer Science section.
