Accurion UltraBAM
Brewster Angle Microscope: Overall Focused Images in Live View
Accurion UltraBAM
Description:
The Accurion UltraBAM is the ultimate Brewster Angle Microscope designed for the air/liquid interface. It allows the direct visualization of Langmuir monolayers or adsorbate films. It also works on dielectric substrates like glass, quartz or similar materials.
Precision Imaging for Insights at the Air/Liquid Interface:
The Accurion 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 motorized analyzer offers the visualization of optical anisotropy, that is e.g. caused by long range molecular orientation order in monolayers. The Accurion UltraBAM is designed to match most troughs available. Regarding best performance and simple handling the large trough is recommended. Vertical position changes of the instrument head are performed by a highly precise motorized lift.
Key Features:
- Spectroscopic imaging ellipsometry from 190/250/360 nm to 1000/1700 nm
- Highest lateral ellipsometric resolution of 1 µm, allowing to determine thickness (0.1 nm to 10 µm) and refractive index on microstructures as small as 1 µm
- Ellipsometric enhanced contrast images for a live visualization of the sample
- Intuitive selection of measurement region by drawing region in live view
- Parallel measurement of multiple regions within the selected field of view
- Enlarge your measurement possibilities by using addition accessories, e.g. cells, temperature control or liquid handling
Specification:
