ROMER Absolute Arm with External Scanner

ROMER Absolute Arm with External Scanner

High-end 3D Laser Scanning

Designed for use with the advanced HP-L-20.8 laser scanner, the ROMER Absolute Arm SE delivers first-class scanning performance on even the most complex surface types.

Featuring unique ‘flying dot’ technology, the HP-L-20.8 can scan multiple surface colors in a single pass. This technology allows point density and even laser stripe width to be modified by the user at any time, ensuring maximum scan detail is guaranteed where it’s needed most, unlike with most handheld scanners – it’s like having multiple scanners in a single sensor.

The accuracy of the complete scanning system is fully verifiable and traceable, ensuring users always have complete confidence in the exactness of their measurements.
