Battery power option
The Leica Absolute Scanner LAS-20-8 can be used on battery power and requires just a single network cable, offering complete portability for laser scanner measurements on the move.
Automatic adjustments for surface type
The ‘flying-dot’ operating concept enables the LAS-20-8 scanner to automatically adjust laser intensity to the surface type, ensuring the best possible reading with no additional user workload.
Self-identifying sensor
The LAS-20-8 laser scanner is automatically recognised by the Leica Absolute Tracker AT960, allowing you to make quick changes between 3D scanning, probing and reflector measurements.
On-scanner measurement profile change
Customisable pre-set scanning modes can be selected from the LAS-20-8’s main switch, giving you access to the right measurement profile at the right time without making adjustments in the software.
Multisensory feedback
The LAS-20-8 laser scanner combines haptic, acoustic and visual feedback to guide you to the optimum measurement position with the minimum of training.
Robust IP50-rated design
Designed for robustness and durability in tough workshop conditions, LAS-20-8’s IP50 ingress protection rating gives you the ability to apply laser scanning measurement wherever you need it.
RDS software interface
Based on the same proven RDS software interface as Hexagon portable measuring arms, LAS-20-8 enables you to draw on existing expertise for system checks, compensation and certifications.
