Omni silver TERS probes

Horiba Scientific’s Omni silver TERS probes for nanoRaman systems enable all modes of TERS operation: top, side and bottom optical access. They are made of bulk noble metal (STM tips) or with a multilayer coating on AFM tips. When used with nanoRaman systems they are guaranteed to produce Raman signal enhancement at 633/638 nm on a reliable test sample. Tests have shown that the probes can reach >40 times improved contrast (tip down, near-field Raman), versus tip up (far-field Raman), leading to an enhancement factor up to 106.
