Nutfield's 3XB 3-Axis Scan Heads offer laser system designers smaller spot sizes and larger scan field sizes than can be achieved with f-theta lenses. Our 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 (patent pending). 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. Lens sets are custom selected for your laser to accommodate for different laser beam apertures and wavelengths and to optimize spot size and field size requirements.

The 3XB scan head can be configured for different apertures, scan angles and wavelengths. They are available with digital or analog electrical interface options.

Advanced laser / scanner PC based control electronics and software are available to support the full range of your integration requirements.

Throughout the assembly process, all NTI scan heads are run through a battery of tests and must pass an extensive over night burn-in. Each head makes witness marks before leaving NTI. Component information and performance data in is stored in a device history record.

3XB scan heads feature NTI's reliable and most accurate RS-15 and QS-30 galvanometers with exclusive ceramic rotor technology for superior performance.
