Brewster Angle Microscope BAM 300

BAM (Brewster Angle Microscopy) visualizes 2-D structures in monolayer films, as monolayer patches differ in refractive index from the surrounding area.

The BAM 300 uses a laser and a CCD camera to provide real-time images on Langmuir films at the air/water interface or on dielectric substrates. Live video imaging at a lateral resolution of 1 μm and at speeds of up to 25 images/sec are displayed on the computer screen while the data is recorded to the hard disk. Compared to other characterization methods, KSV's BAM is a powerful and economical technique for non-invasive (non-contact) study of your thin films.

The KSV Optrel BAM is compatible with all KSV Langmuir Blodgett troughs. However, KSV provides a dedicated KSV20001BAM trough which is specially designed for BAM applications.

The Brewster Angle

The Brewster angle is defined as the angle at which the intensity of the vertical component of reflected linearly polarized light passes through a minimum. The Brewster angle is controlled by the refractive indices of the materials in the system. For example, the Brewster angles for the air/water, air/glass and air/diamond interfaces are 53°, 57° and 67.5° respectively.
