Zweidimensionale optische Nahfeldlichtquelle

摘要

The invention concerns a near-field light source, especially for background illumination of a probe (4) in a microscope, with a support member (1) with a hollow channel (2) which essentially runs parallel to the direction of light emission and is at least partly filled with an excitonically active material (3) as well as with a radiation source (6) which is on the observe side from the sample for exciting the excitonically active material (3) to emit light. The support member (1) exhibits a number of contiguous hollow channels (2) which run essentially parallel to the direction of light emission and which are at least partly filled with an excitonically active material (3).
