3D scanner is three times faster

Metris is launching the LC60D next-generation digital 3D line scanner. Equipped with state-of-the-art digital technology and powerful on-board data processing, the LC60D scanner is claimed to more than triple today's common scan rates.

With the release of LC60D, Metris says it further extends its tradition of introducing ground-breaking scanner innovations. A major leap forward compared to its LC50 predecessor line, the new scanner offers a significant increase in productivity, which is achieved by speeding up the image acquisition frame rate from 25 to 75Hz. In combination with 15 per cent wider laser stripe and 17 per cent higher point resolution, the scan speed of the LC60D reaches 75,000 non-interpolated points per second.

A large number of measurement points radically increases the surface area the scanner is able to capture and process in a given time. As a result, operators can complete scanning jobs up to three times faster. This allows manufacturers to compress the inspection cycle time for freeform parts, or boost the number of features that can be scanned in the same time frame.

To scan surfaces with varying colour or high reflectivity effectively, Metris is introducing third-generation Enhanced Sensor Performance (ESP3). By dynamically adapting laser source intensity and CMOS camera sensitivity, the LC60D automatically captures any gradual or abrupt change in surface characteristics. ESP3 functionality not only provides automatic real-time adjustment of sensor settings between successive laser stripes, but also for each individual point of the laser stripe. This ensures maximum data coverage on all surface materials and shapes, irrespective of surface finishing and lighting conditions.

Metris development engineers optimised the scanner design for operational stability and robustness by eliminating moving parts and mounting principal components in an ultra-stiff stress-free aluminium housing.

Furthermore, the LC60D is designed for premium temperature stability, which, together with the temperature compensation algorithms, minimises warm-up time and guarantees reliable accuracy under shop floor conditions. The LC60D scanner even has zero warm-up time when it is taken from the heated ACR3 docking rack, resulting in minimum idle time and maximum scanning productivity.

The LC60D scanner has been designed to easily integrate onto both Metris and other leading brand CMMs. Additionally it can also be used in conjunction with portable CMMs including both articulated arms and optical CMMs. The Metris Focus software suite accelerates the entire workflow, from off-line preparation to final reporting. Focus Scan supports intuitive CAD-based generation of scanner motion paths, and Focus Inspection generates manual or automatic reports that display interactive 3D part-to-CAD or feature inspection results.
