The HDV500 Digital Video Comparator offers the best features of a large horizontal optical comparator and a vision metrology system. Configured like a traditional horizontal comparator, the HDV500 has a long travel X-Y stage and heavy-duty steel construction. The work stage is the same as the popular HF600 and HF750 comparators, with a 330lb (150kg) load capacity. Much like the HDV300 and 400, the heart of the system centers on a uniquely designed interchangeable lens mounting system coupled to a hi-resolution color digital video camera (patent pending). The system is available with a choice of three telecentric lenses. The HDV systems house a powerful 64-bit PC, which runs MetLogix M3 Metrology software. With this software, DXF CAD files can be imported and 2D Go-No-Go “profile gages” can be developed directly from the CAD files. Video-Edge-Detection (VED), allows real-time interaction of the imported file with the video image of the part being inspected.
