Altechna Axicon Lens
Flat-type achromatic lens with high precision and high damage threshold (wavelength range 330-2000nm, maximum clear aperture diameter 15mm)
This flat-type axicon lens can convert a Gaussian beam into a Bessel beam, forming a deep focal depth and ring-shaped beam. Additionally, this product features a high damage threshold and has laser irradiation resistance similar to uncoated quartz substrates. It is ideal for applications such as micromachining, ultra-high aspect ratio micro-hole processing, high Bragg gratings with 90% efficiency, and cutting of transparent materials. An optional double-sided AR coating is also available. For more details, please contact us or download the catalog.
basic information
■Negative Bessel Beam Region The polarization of the incident light becomes larger in right-handed circular polarization compared to a concave axicon lens. ■Positive Bessel Beam Region The polarization of the incident light becomes larger in left-handed circular polarization compared to a concave axicon lens. ■Positive and Negative Bessel Beam Region The polarization of the incident light becomes larger in linear polarization compared to when both positive and negative axicon lenses are used simultaneously. ● For more details, please contact us or download the catalog.
