About This Product

A flat axicon (circular grating) is a spatially variable retarder that converts a Gaussian beam into a Bessel Gaussian beam. By creating an internal structure, it has the same reliability and high damage threshold as a regular quartz substrate. Positive and negative Bessels can generate thin zones separately, corresponding to LHCO polarization and RHCP polarization. In the case of linearly polarized light, positive and negative zones can be generated simultaneously.

■Features

・High damage threshold: 63J/cm2 @1,064nm 10ns, 2.2J/cm2 @1,030nm 212fs ・High transmittance: 94% @1,030nm, 92% @515nm, 85% @343nm (reflectance without AR coating) ・Large diameter: maximum Φ15mm ・Supports wide wavelength range: 330-2,000nm ・Diffraction efficiency: 95% ・Positive/Negative

■Applications

・Laser micromachining ・Ultra high aspect ratio micro drilling ・High efficiency Bragg grating ・Cutting transparent materials
