Atlas Triangulation Sensor


Miniaturised laser triangulation sensor for compact environments

The ATLAS Series of miniaturised laser triangulation sensors are compact, accurate sensors for measurement of displacement, distance or height, or thickness when combined in pairs.

The intelligent signal processing controls exposure of the CCD array and laser power in real time, resulting in excellent dynamic behaviour regardless of varying colour, reflectivity or texture of the target, making them a solid choice for integration for online or offline measurements.

The ATLAS sensors are compact and lightweight with an extremely high resolution and high rates of precision on most surface types. Depending on your needs, Scantron can also provide supporting software for data collection and visualisation.

Non-contact surface measurement applications

ATLAS miniaturised lasers can be used in a number of different compact environments across a multitude of applications. Uses include non-contact surface measurement of flatness and straightness, multi-track differential thickness measurement and face profile measurement of coils.
