He. Debruijn et al., SURFACE-PLASMON RESONANCE MICROSCOPY - IMPROVEMENT OF THE RESOLUTION BY ROTATION OF THE OBJECT, Applied optics, 32(13), 1993, pp. 2426-2430
A new surface plasmon resonance microscope is described that can opera
te at different resonance angles. The lateral resolution in the surfac
e plasmon resonance microscope depends on the orientation of the edge
of the object relative to the plasmon direction. By rotating the objec
t it is possible to reach a resolution of the order of the wavelength.
The equipment is described, and it is shown that a resolution of 1.5
mum is obtained for a silver-air interface with 675 nm. Some pictures
of biological cells are presented.
