Description

Procurement of scattering-type near-field optical microscope (VIS-neaSCOPE) that enables simultaneous background-free imaging and spectroscopy on nanometre length scales in the visible range.

Total Quantity or Scope

Neaspec (attocube) is the only company worldwide, who manufactures 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. Their exclusive design works with the following patents: - 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 - Patend phase shifting (PhS) detection to extract relative phase These patents and the exclusive design have enabled the VIS-neascope system to conduct amplitude and phase-resolved vector field, reflection and absorption mapping with nanoscale spatial resolution. It is currently the only system on the market that enables dual-port operation combined with a high NA parabolic mirror, which is essential for low SNR pump-probe measurements in the visible range. The VIS-neascope system is also the only system offering pseudoheterodyne background-free detection of the amplitude and phase of the near-field signal up to the 5th harmonic order, which is another essential requirement for s-SNOM in the visible range. In addition, the vis-neaSCOPE offers the following unique technical specifications: - 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. The system is also flexible and can be upgraded to operate in other wavelength ranges (out to THz range), perform electrical measurements, nano-PL, nano-Raman and photothermal expansion mapping in the future. In particular, neaspec is the only company who can upgrade the existing cryogenic s-SNOM system (cryo-neaSCOPE) based at University of Manchester and integrate a visible illumination unit to perform nanoscale imaging and spectroscopy at low temperature.
