PROBLEM TO BE SOLVED: To provide an apparatus for determining angular distribution of radiated light, and in particular to provide a user with rotational symmetry essential for a principle in measurement, because cathodoluminescence generated in a scanning electron microscope brings an advantage of localized excitation of individual microscopic structures and, when luminescent structures are characterized, intensity, wavelength, polarization and angular emission of the luminescence are all of interest.SOLUTION: The apparatus is compatible with additional polarization filtering and spectral bandpass filtering methods used to characterize the luminescence and understand a specimen. |
