From: Quantifying the magnetic nature of light emission

Figure 4

(a) Schematic showing the excitation and detection paths for the pump light (green) and collected luminescence (red), respectively. Individual components include the 1.3 NA oil immersion objective, short pass filter (SPF), dichroic mirror (DM), long pass filter (LPF), tube lens (TL), flip mirror (FM), polarizer (Pol) and Bertrand lens (BL). Circled letters indicate the spatial position of the subpanel illustrations: (b) example BFP image recorded directly on a CCD camera, (c) illustration of the BFP image projected onto the entrance slit of the spectrograph and (d) example BFP spectrum recorded on a CCD mounted at the spectrograph exit port.
