UVFS Axicon Lenses
An axicon lens consists of one conical surface and one plano surface, also commonly known as a rotationally symmetric prism. It is primarily employed to generate Bessel beams and ring-shaped laser beams.
This series of axicon lenses is fabricated from fused silica, featuring high hardness, low refractive index and excellent thermal stability. Supplied uncoated, they support transmission across ultraviolet, visible and near-infrared spectra, making them ideal for high-power laser applications. Three apex angle options (β) are available: 0.5°, 2° and 5°. An arrow mark on the lens edge indicates the orientation of the conical surface.
