6. Introduction
This manual covers the installation and use of the 3XB, 3-Axis Scanning System.
Nutfield’s 3XB is designed to deliver large field sizes up to 2000mm without the use of large
scanning lenses, XY tables, or gantries. These field sizes are achieved while delivering equal to
or better, field-size/spot-size ratios then those of standard laser scanning lenses. The integrated
design leverages the best of NTI's galvo technology to offer superior bandwidth, accuracy and
flexibility in 3-axis technology.
The 3XB is the only 3-Axis Scan Head, which offers different field and spot size combinations
by simply turning a knob to adjust the spacing between the translator and objective lens. The
lens translator houses an expander lens, which accepts a beam from the laser source. The beam
expands and then travels through an objective lens, which lies in front of the X/Y scan mirrors
in a post objective scanning configuration.
The expander lens moves linearly along the axis of the beam to correct for focus, in real-time,
as a function of an X/Y position within the scan field. Nutfield offers standard lens-sets with
prescribed input beam diameters. Lens-sets are available for 266nm, 355nm, 532nm, 1064nm,
10.6um, and
Dual Wavelength 532nm and 1064nm . A full complement of fixed beam
expanders is also offered to properly adjust the laser’s beam size for the optical design.
Correction files are critical to any scanning application; 3-Axis systems are no different.
Further, 3-Axis systems require a 3
rd
, Z-Axis focus correction. CorCalcII is a utility offered
with 3-Axis systems to ease the generation of correction files, and also allow the operator to
quickly adjust working distances, and field sizes to optimize the system’s spot size for the
application.
3-Axis systems are designed to operate seamlessly with Nutfield’s WaveRunner Laser
Scanning Software, and Surfboard Laser Scan Controller Hardware.
