AccuProfile 820 2D Laser Scanner

AccuProfile 820 2D Laser Scanner

The AP820 2D laser scanner series offer a large selection of case sizes, measuring ranges, and diode/accessory options to be used in a wide range of measurement applications. The 2D/3D sensor performs very well on shiny or jagged targets and in environments with high ambient light. The sensor’s auto gain and high dynamic range allow for measurement in complex applications, even edge scanning on sharp targets.


High accuracy sensors and Laser Line Triangulation Principle

AccuProfile™ 820 Laser Scanners use high accuracy sensors to determine displacements and surface heights by emitting a triangulation measurement beam of visible laser light that creates a line on a target surface. Reflected light from the surface is viewed at an angle by a two-dimensional detector inside the sensor. The two-dimensional contour profile is calculated by the scanner’s microprocessor from the pixel data from the diffusely – reflected laser line. The contour profile is transmitted through Ethernet communications to a computer. Real-time 3D profiling is created by synchronizing the position of the scanner with encoder inputs from conveyors, linear stages or robotic movements. A variety of models are specified, each to allow a different measurement range and field of view.

Compact Design for Measurement of Complex Surfaces

The Acuity AP820 laser scanners perfectly meet all requirements for a large range of measuring applications, allowing flexible integration even into difficult environments.  A particular benefit of the AP820 2D-3D laser profiler is their high stability against interaction with extraneous light. The scanner’s sophisticated CCD detector affords the highest dynamic optical range, allowing these devices to measure almost any kind of opaque surface, shiny or matte, bright or dark. Additionally, the sensor performs well on sharp edges and transitions, where other sensor may produce noisy results. All of this is achieved through relatively low laser powers and permissible laser classes.
