CAN - sSNOM for University of Manchester

Tender description

NPL has a requirement for a scattering-type near-field optical microscope (VIS-neaSCOPE) that enables simultaneous background-free imaging and spectroscopy on nanometre length scales in the visible range. Lot 1: A scattering-type near-field optical microscope (VIS-neaSCOPE) that enables simultaneous background-free imaging and spectroscopy on nanometre length scales in the visible range. - Patented parabolic mirror design for focusing and collection of light - Patented dual-port design to allow two beams of light to be focused on the atomic force microscope (AFM) tip for nanoscale imaging and spectroscopy - Patented signal processing for optical background suppression - Patented pseudo-heterodyne detection (PsHEt) technology for background suppression - Patented interferometric design (nano-FTIR) for background-free optical detection technology and simultaneous detection of optical amplitude and phase and hyperspectral imaging - Patented high speed holography (HSH) for multispectral imaging - Patened phase shifting (PhS) detection to extract relative phase - Optimised scanning probe microscope system that can be combined with mechanical and electrical measurements - Built-in optical imaging and spectroscopy software modules, as well as data visualisation and analysis software - Position sensors for motorised parabolic mirror axes to enable alignment-free focusing of a laser beam to the AFM tip - Visible and NIR illumination units, which can be integrated and coupled into both the room-temperature and cryogenic temperature s-SNOM system.
