Axicon optical flat

Flat Axicon - transforms Gaussian beam into a Bessel-Gauss beam. Circular grating, or better known as flat axicon, is a space-variant retarder that transforms Gaussian beam into a Bessel-Gauss beam. Flat Axicons delivery in 2-4 weeks Technical Features: Positive and negative Bessel-Gauss zones – 3 in 1 usage possibilities (min. apex angle: 176-179.9° @ 1030 nm) Suitable for high LIDT applications and high-power lasers (63.4 J/cm² @ 1064 nm, 10 ns and 2.2 J/cm² @ 1030 nm, 212 fs) High > 93% transmission @ 1030 nm (with AR coatings transmission > 99%) Flat optics – saves space, easy to handle, no additional optical elements needed Reliable and resistant surface – the structure is inside the bulk Large structured aperture possible – up to 15 mm (standard substrate size Ø 25.4 x 3 mm) Wavelength from 330 to 2000 nm
