• Hexagon AS1 Absolute Scanner 3d laser Kit
• CP-C Installed
• Magnetic Base with Mounting Ring

Specifications:

• Manufacturer: Hexagon Metrology
• Model: Absolute Arm 8540 – 7-Axis Portable Measuring Arm
• Year: 2022
• Type: Portable Coordinate Measuring Machine (CMM)
• Axes: 7-Axis articulating arm system for tactile probing and 3D scanning
• Measurement / Reach: Arm length ~157″ (approx. 4.0 m) measurement volume (typical for 8540 range)

Designed for high-end industrial inspection, reverse engineering, and CAD-to-part comparison, this 7-axis portable coordinate measuring machine (CMM) combines ergonomic mobility with uncompromising accuracy across its massive 4.0-meter measuring envelope.

Equipped with absolute encoders that eliminate warm-up times and homing routines, the 8540 model allows operators to start measuring immediately upon setup. Its 7-axis movement offers full rotational freedom, making it easy to maneuver tactile probes or laser scanners around complex workpieces and tight angles without repositioning the base.

Key Features

• 4.0-Meter Measuring Range: Accommodates large-scale components, assemblies, and fabrications in a single setup.
• 7-Axis Articulation: Ergonomically balanced 7-axis wrist movement designed for effortless, fluid probing and seamless integration with non-contact laser scanners.
• Absolute Encoders: Immediate system startup without encoder reference passes or homing routines—just turn on and measure.
• Modular Probe Architecture: Quick-change probe capability allows rapid swapping between tactile probing and high-speed optical scanning without recalibration.
• Rugged Shop-Floor Design: Built with carbon-fiber structure to resist thermal expansion and withstand harsh manufacturing environments.
• Audited & Calibrated: Fully inspected, tested, and pre-calibrated to guarantee ISO-compliant measurement precision out of the box.

Common Applications

• Quality Control & First-Article Inspection: Verify complex geometries, castings, and machined parts against CAD models to catch defects early.
• Reverse Engineering: Capture high-density surface point clouds on existing parts or prototypes to generate accurate 3D CAD files.
• In-Process Shop-Floor Metrology: Bring the inspection tool directly to the CNC machine or assembly line, minimizing transit time for massive or heavy components.
• Tooling & Fixture Alignment: Precisely inspect, align, and calibrate manufacturing jigs, welding fixtures, and stamping dies.
