Cantilever-based NSOM/SNOM probes

We produce cantilever-based probes for near-field scanning optical microscopy (NSOM, also known as SNOM) with customized aperture size. The solid silicon tip of AFM cantilevers is replaced by a hollow pyramid with an aperture size which can be adapted to meet application specific demands. The most commonly used sizes are 50 nm and 100 nm. Compared to fiber-based NSOM probes, the cantilever-based probes show much higher light transmission, up to a factor of 100 and puts the user in a position to probe the topography of surfaces with a resolution comparable to standard AFM.

Our cantilever-based silicon probes utilizes a hollow, aluminum-coated, pyramidal tip with a small aperture at the apex to focus the SNOM beam. Aluminium-coated tip
