HALscan 20.20 - 20 mm Aperture XY3-100 Scanhead

Please note: Our annual vacation close-down takes place from 22.05.2024 until 08.06.2024.
There will be no support and no shipping during this time.

The HALscan 20.20 galvo scanner is an high-speed laser galvo scanhead which can be used with high laser power, comes for an extremely competitive price and is certified to support the new, open and future-proof XY3-100 digital scanner interface with 20 bit resolution. This scanning head is fully adjusted, ready to use and only needs to be electrically connected for operation. It provides the following features:

  • 20 mm aperture
  • optional water-cooling
  • XY3-100 input signal
  • optionally a close to linear behaviour operation mode can be enabled, removing the necessity to use a correction table
  • high 20 bit digital resolution
  • position extrapolation in case of data transmission errors to avoid random burn-in points
  • standard +-15 V power supply
  • simple 1:1 connection with E1803D controller card possible via standard D-SUB25 cable
  • simple 1:1 connection with E1701D controller card and E1701dock possible via standard D-SUB25 cable
  • full operation with any other XY3-100 scanner controller
  • low idle power consumption
  • available for all relevant laser types/wave lengths
  • industry-standard mounting interface

The XY3-100 protocol itself is a new, open, future-proof and non-proprietary standard for communication between scanner controller card and scanhead. It provides variable position resolutions in range 16..26 bit and an extended backchannel. It is hardware-compatible to its predecessor XY2-100 and therefore can be implemented by scanhead-vendors in existing hardware simply via a firmware upgrade.
