*The OmegaScopeTM 1000 is a state-of-the-art turn-key solution that combines confocal NanoRaman/ Fluorescence spectroscopy and ultra resolution multi-range research AFM enabling TERS (Tip Enhanced Raman Scattering) mapping. It is available in both transmission and reflection configurations providing direct top, bottom and side optical access. The flexibility of the OmegaScope platform offers almost endless possibilities in correlation of high spatial resolution Raman and AFM data.
 Open Design for Multiple Optical Access. NanoRaman for TERS and SERS Measurements.
- AIST-NT’s AFM has been designed so that it can easily be integrated with optical instruments such as Raman spectrometers, UV-VIS adsorption spectrometers etc. The open design of the AFM head makes it possible to have high quality optical access from the top (100X, 0.70 NA), side (20X, 0.42 NA) or bottom (using any commercially available objective, including immersion objectives).
- Side illumination becomes very important in the case of TERS (Tip Enhanced Raman Scattering) and scattering SNOM experiments because with side illumination it is easy to have a significant Z component of the optical field. It also may be very valuable for investigation of SERS (Surface Enhanced Raman Scattering) structures. Precise alignment of the side and top (bottom) objectives enables experiments that involve investigation of the influence of illumination conditions on TERS and SERS efficiency.
- AIST-NT’s AFM head includes a 1300nm registration laser, which eliminates cross-talk with the most popular Raman lasers up to 1064 nm. The IR registration laser also allows for work with visible light-sensitive semiconductor and biological samples.
 Optical Input-Output System Optimized for TERS and SERS measurements
- Top and side illumination (10X-0.28NA/100X-0.70NA; 20X-0.42NA).
- Raman and fluorescence measurements on the same sample area.
- Optimal illumination conditions for TERS experiments on non-transparent samples.
