Off-axis parabolic mirror optics for polarized Raman spectroscopy at low temperature
Off-axis parabolic mirror optics for polarized Raman spectroscopy at low temperature
We report the development of a detection optics for the integration of Raman scattering and scanning probe microscopy at low temperature based on a parabolic mirror. In our set-up, half of the paraboloid mirror covers a solid angle of π corresponding to a numerical aperture of N.A. ≈ 0.85. The …
