OmegaScope

The HORIBA OmegaScope is a dedicated platform for tip-enhanced Raman spectroscopy (TERS) and near-field optical spectroscopy, providing chemical imaging and spectroscopy with nanometer-scale spatial resolution. The OmegaScope overcomes the fundamental spatial resolution limit of conventional Raman microscopy by using a nanoscale metallic tip to locally enhance and confine the laser field at the tip apex, allowing Raman spectra to be collected from a nanometer-scale sample volume. This TERS approach combines the molecular identification power of Raman spectroscopy with the spatial resolution of atomic force microscopy – typically achieving resolution of 10-20 nm or better depending on tip quality and sample. The OmegaScope system is compatible with HORIBA Raman spectrometers (LabRAM series) and can operate in contact, tapping, and non-contact AFM modes. It supports both bottom-illumination (transparent samples) and side/top-illumination (opaque samples) configurations, making it applicable to a wide range of materials. TERS applications include single-molecule vibrational spectroscopy, nanoscale chemical mapping of 2D materials and surfaces, biological membrane imaging, polymer blend interfaces, and semiconductor defect mapping. NewRoad provides the HORIBA OmegaScope in Israel for researchers requiring true nanoscale chemical imaging beyond the diffraction limit.
