The axicon lens, with its cone-like shape, is capable of generating Bessel beams, which exhibit an annular beam profile. The diameter of this annular beam is influenced by the apex angle of the axicon and decreases with the distance from the apex angle to the image plane. Importantly, the width of the annular beam remains constant. This article delves into the mechanisms of axicon-generated Bessel beams and their applications in various fields, including medical, research, and measurement technologies.
