IBS optics for high-power lasers in material processing

Laseroptiken für die Materialbearbeitung

Increase in laser fluence requires new coating options

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

Navitar's exclusive adapter for coupling to your digital camera or camcorder.

Achromatic waveplates consists of two plates.

Aspherical lenses correct aberrations, which in monochromatic light include image sharpness errors and distortion.

A typical application of these lenses is the focusing of a collimated beam onto an optical fiber.

The ideal system for high magnification vision applications.

Additional components for the expansion of a laser system: Here you will find beam expanders, z-axes Shift, and beam tubes.

Laser beam directing components direct or deliver the laser beam to the workpiece.

Beam splitters for separating a beam into two equal parts without changing the polarization

Non-polarizing beam splitters split the incident light with an R/T ratio of 50%. They are designed for exactly one wavelength and do not have any influence on the polarization of the beam to be split.

Brewster plates are used to separate s- and p-polarized light.

Brewster plates have a rectangular shape and are inserted at a specific angle of incidence to the laser beam. Light that is polarized parallel to the plane of incidence/reflection is completely transmitted at Brewster’s angle, whereas about 50 % of s-polarized light is transmitted.

Broadband filters allow wide wavelength ranges of incident light to pass through; in selected regions of the spectrum, these filters block the light.

Cavity end mirrors are used to generate the laser beam in the resonator.

Resonator end mirrors, also known as cavity mirrors, are designed to have high reflectivity at the desired laser wavelength in order to maximize the efficiency of the laser.

ROUND AND RECTANGULAR CYCLINDER LENSES ARE USED TO CREATE LINES / BEAM EXPANSIONS IN ONE DIRECTION.

We offer plano-concave and plano-convex cyclindrical lenses in rectangular, square, and round form.

DIAGNOSTIC BEAM SPLITTERS FOR PROCESS MONITORING

Dichroic mirrors separate or combine two or more beams of different wavelengths in the desired ratio and enable process monitoring on the operating level in several wavelength ranges, as well as beam diagnostics. Their complex design enables multiple transmission and reflection ranges.
