摘要：

A new surface plasmon resonance microscope is described that can operate at different resonance angles. The lateral resolution in the surface plasmon resonance microscope depends on the orientation of the edge of the object relative to the plasmon direction. By rotating the object 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.
