Wavelength Range

Each scan system is equipped with appropriately coated mirrors and objectives (or varioSCAN focus units) suitable for the laser's wavelength, power and pulse length.

SCANLAB offers optical components for all laser types commonly used in laser materials-processing over the wavelength range from 193 nm to 10.6 μm, and for laser powers up to over 5 kilowatts.

Working distance

Working distance A is the distance between the entrance aperture's central axis and the working plane. A is determined by the focal length and mounting position of the F-Theta objective (if present). For prefocus systems, working distance A is determined by the dynamic focusing unit in the null position ("z=0" plane).

Free working distance A' is the mechanical distance between the scan system (bottom edge of housing including objective) and the "z=0" working plane.
