Description
Beamera presents Bessel Beam Shaper – an objective designed to conveniently transform Gaussian beam into ready-to-used Gauss-Bessel beam. It features four main advantages that help to stand out from the competition:
· High damage threshold (LIDT is only limited by coating)
· Negative, Positive or double Bessel-Gauss zones at the output
· Easy alignment – mounts into standard cage system
Bessel Beam Shaper is available for 1-st, 2-nd & 3-rd harmonics of both Neodymium and Ytterbium laser lines.
The device is designed to comply strict stability, robustness requirements that are inflicted by industrial lasers applications, which makes it suitable for both – industrial and demanding scientific use.
Main applications for the Bessel Beam Shaper are processing of transparent materials (e.g. drilling, cutting, Writing Bragg gratings).
