A Unique Angle Microscope
Abstract
In BCEIA’99 NFT’s exclusive Brewster Angle Microscope was prominent. As it set up the international standard technique to monitor and analyze ultra-thin organic films, the microscope were widely used. It has a powerful laser a powerful laser light source, and its excellent resolution enables it to assess the images that are usually impossible for other microscopes. Brewster Angle Microscope is primarily used to observe:
Monolayer phases
In-situ polymerization in monolayer
Transformation from monolayer into multilayered structures
Influences of various subphase compositions on monolayer structures
Photochemical reaction
LB-film on solid structures and its homogeneity
Absorption kinetics, polymers and other materials that cannot be detected by fluorescence microscopy
