Beam guidance element has reflective surfaces for generating hollow beam from solid beam (or vice-versa) has odd number of reflective surfaces used for beam deflection
Beam guidance element has reflective surfaces for generating hollow beam from solid beam (or vice-versa) has odd number of reflective surfaces used for beam deflection
The rotation-symmetrical Axicon beam guidance element has reflective surfaces for generating a hollow beam (2) from a solid beam (1) (or vice-versa). An odd number (minimum three) of reflective surfaces are used for beam deflection so that the characteristics of the electric field perpendicular to the propagation direction over the beam cross-section are restrained.
