The LBTEK Bessel Processing Head is an optical module for the terminal of laser processing systems. It consists of refractive and diffractive optical elements assembled inside a metal mechanical barrel. By means of light‑field modulation from an axicon lens and beam shaping of the double‑telecentric optical system, it generates Bessel beams that meet laser‑processing requirements.
