Simulation of an Optimal Radiation Injection/Extraction Optical System for Effective Tip Enhancement of the Electromagnetic Field in Opaque Samples
Competitive schemes for constructing an optical system for a combination of a scanning probe microscope and an optical microspectrometer are examined, which make it possible to study opaque samples by the method of tip-enhanced Raman scattering. Taking into account the presence of a scanning microscope probe, optimal lenses are selected for implementing each scheme. The efficiency of using each optical scheme both for exciting a Raman signal and for collecting secondary radiation is quantitatively evaluated. As a result, the most effective optical system is revealed for achieving the optimal excitation/collection parameter.
