The experimental setup. ND filter: neutral density filter. The blue line represents the excitation light; the green line represents the fluorescence emission. The scattered fluorescence signal is directly imaged onto the camera via objective lens. The magnification is given as the image distance divided by the object distance. The filters in front of the camera transmit the fluorescence and block the laser light
