EP³-BAM Brewster Angle Microscopy EP³-BAM: the latest member of the BAM family Since its first presentation at the LB 6 in Paris, Brewster Angle Microscopy (BAM) has been established as a worldwide standard technique for the investigation of ultra-thin organic films. Nanofilm's BAM1 was the first commercial instrument available. Based on our EP³ imaging ellipsometer, the EP³-BAM provides the latest imaging technology for unsurpassed BAM imaging. Cooperation with other companies in the field, resulted in the development of a range of interdigitizing products providing tailored solutions for thedemands of state-of- the-art research in organic films. General description The EP³-BAM is a thin films imaging system. It is a completely ”hands-off” computer-controlled system, using proprietary motor control circuitry. The EP³-BAM displays the real-time image of the sample directly on the computerscreen and features important image processing functions. A focus 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, close to the physical limits of this technique. The EP³-BAM uses the powerful EP³View software (under WindowsXP), making operation easy and convenient. As a complete solution, the system comes including the computer and all necessary software.

However, an amazing trick of optics is the possibility of having zero reflection. This well-understood phenomenon is
