Zeiss 3D Scanning - Comet and t-Scan

For the 3D Scanning of freeform surfaces PADT is pleased to offer two innovative system families from ZEISS Optotechnik. They represent a new system generation for flexible and mobile use: the COMET® systems, COMET 6, COMET L3D, COMET and COMET Automated, based on fringe projection (blue light), and the handheld laserscanner T-SCAN CS and T-SCAN LV with a tracking volume of up to 35 m3.

Before offering ZEISS scanners, PADT used their systems for our scanning services. We found that they provided outstanding accuracy, were easy to use, and provided the speed we needed to satisfy our customer's tight schedules. These scanners works, and they works well, and are the foundation of our 3D Scanning services offering.

PADT offers both laser and blue light solutions, along with the colin3D software.

Comet Blue Light Scanning

This technology uses a technique called Structure-light 3D Scanning that projects a band of light onto a three dimensional object. A scanner records the distortion of the band and creates an exact mathematical representation of the object being scanned. PADT offers two COMET solutions:
