HALscan 10X20 - XY3-100 Scanhead

The HALscan is a low-cost but high-accuracy scanhead which is certified to support the new, open and future-proof XY3-100 digital scanner interface. It is fully adjusted, ready to use and only needs to be electrically connected for operation. It provides the following features:

• 10 mm aperture
• XY3-100 input signal
• close to linear behaviour, as nearly no pillow distortion exists, for many applications no correction table is necessary
• high 20 bit digital resolution
• position extrapolation in case of data transmission errors to avoid random burn-in points
• +-15 V power supply
• simple 1:1 connection with E1803D contoller card 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 in existing hardware simply via a firmware upgrade.
