Abstract

We report bright-field and dark-field surface-plasmon imaging using a modified solid immersion lens and a commercial objective of moderate NA in the epi configuration. The contrast and resolution are extremely good, giving well-resolved images of protein monolayers both in air and in water. We also describe a two-part solid immersion lens that allows the sample to be moved without degrading the image quality in any observable way. The merits of the two-part lens are discussed and compared to commercially available microscope objectives. Finally, we introduce a simple Green's function model that illustrates the key features of both bright-field and dark-field surface-plasmon imaging.
