We have measured 200 eV electron transmission through a single platinum tube of a diameter of 3.3 mm. We find that the transmission of electrons can be detected even at large tilt angles, where the tube is not transparent geometrically. The transmission drops down exponentially with increasing the tilt angle. The energy spectrum of detected electrons behind the tube contain contributions at lower energies due to both inelastic scattering and secondary electron emission. The spectrum is qualitatively in good agreement with the calculations performed for the flat Pt surface in order to understand and model the electron interaction processes that define the transmission and the energy spectrum at the exit.
