High-power lasers in femtosecond cycles- optics for laser material processing are subject to very different technical requirements. The IBS (ion beam sputtering) process offers manufacturers many options for achieving parameters that cannot be achieved with conventional coating methods, e.g., at high laser fluence.

Product Overview
Beyond Borders
Aspherical lenses correct aberrations, which in monochromatic light include image sharpness errors and distortion.
Brewster plates are used to separate s- and p-polarized light.
Cavity end mirrors are used to generate the laser beam in the resonator.
ROUND AND RECTANGULAR CYCLINDER LENSES ARE USED TO CREATE LINES / BEAM EXPANSIONS IN ONE DIRECTION.
DIAGNOSTIC BEAM SPLITTERS FOR PROCESS MONITORING
combine or separate two or more beams with different wavelengths.
The degree of reflection slopes from the center of the optic in a Gaussian distribution.
Optimized for high-power lasers with intense pulse energies or high average powers
Dielectric bandpass filters according to customer specifications. The infrared filters are available in the wavelength range from 1.0 µm to 20.0 µm.
Dielectric coatings. Customer-specific solutions are also available for IR long-pass filters.
Neutral density filters for the IR range from 1.5 µm – 14.0 µm. Neutral gray filters are used in attenuation.
Si, Ge, or InAs wafers with an AR coating. IR semiconductor filters function as long-pass filters with very good blocking.
