Brewster Angle Microscope nanofilm_ultrabam
Overall Focused Images in Real Time
The Ultrabam is the ultimate Brewster angle microscope designed for the air/liquid interface. It allows direct visualization of Langmuir monolayers or adsorbate films. It also works on dielectric substrates like glass, quartz or similar materials.
The nanofilm_ultrabam combines high resolution and overall focused real-time imaging. Advanced imaging optics provide fully focused images at 20-35 frames per second. A high performance camera and specific calibration algorithms enable quantitative measurements of reflectivity. Thus adsorption kinetics or thickness variations can be monitored. The instrument comes with a motorized analyzer to visualize optical anisotropy caused by long range molecular orientation order in monolayers.
The powerful software 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 troughs. The trough comes as a separate item and is not included as standard. As a restriction, the nanofilm_ultrabam is designed as a pure Brewster-Angle-Microscope which cannot be upgraded to an Ellipsometer.
