Digital Scan Heads

Digital scan heads are suitable for applications that demand minimal drift and extremely high positional accuracy and repeatability.
These heads are typically used for high-accuracy industrial laser material processing and are available in 10, 15 and 20 mm apertures.
The digital galvo drivers are not integrated into the scan head, this gives a compact head design and yields a further improvement in drift performance by removing driver-heat-dissipation from the scan head.
Head interface can be XY2- 100 (16-Bit) or 20-Bit advanced protocol with integrated position feedback.
