Моделирование Оптимальной Оптической Системы Ввода/Вывода Излучения Для Реализации Эффективного Зондового Усиления Электромагнитного Поля Для Случая Непрозрачных Образцов

Abstract

Competitive schemes for constructing an optical system for combining a scanning probe microscope and optical microspectrometer, allowing the study of opaque samples by the method of tip enhancement of the Raman scattering intensity, are considered. Optimal objectives for the implementation of each scheme, taking into account the presence of a scanning microscope probe, are selected. The efficiency of usage of each optical scheme is estimated quantitatively for both excitation of a Raman scattering signal and collecting secondary radiation. As a result, the most effective optical system in terms of "excitation / collection“ parameter is revealed.
